Description

Method, device, terminal and storage medium for executing service

Technical Field

The present disclosure relates to the field of internet technologies, and in particular, to a method, an apparatus, a terminal, and a storage medium for executing a service.

Background

In a Remote Direct data Access (RDMA) network, multiple terminals may simultaneously cause a server to perform the same service, e.g., write log data in the same log in the server.

And the server determines the execution condition of the target service through the service execution progress mark. Before a plurality of terminals commonly request the server to execute the target service, each terminal sends an acquisition request for acquiring the mark updating sequence identifier corresponding to the target service to the server, and the mark updating sequence identifier is used when the service execution progress mark in the server is updated subsequently. There is a counter in the server, and the counter value of the counter is incremented by 1 each time the server receives an acquisition request. And the server responds to the acquisition request sent by each terminal, takes the current count value of the counter as a mark updating sequence identifier distributed to the current terminal, and sends a message carrying the mark updating sequence identifier to the current terminal. And then, the current terminal sends a service execution request corresponding to the target service to the server, and the server responds to the service execution request sent by the current terminal, executes the target service and sends a service execution completion message to the current terminal after the target service is completely executed. And then, the current terminal needs to send a mark updating request carrying a mark updating sequence identifier acquired in advance to the server, and the server updates the service execution progress mark according to the sequence indicated by the mark updating sequence identifier. In practical application, the process that the terminal sends the acquisition request for acquiring the mark updating sequence identifier to the server and the server sends the message carrying the mark updating sequence identifier to the corresponding terminal needs to consume a longer time, and instead, the process that the server actually executes the target service in response to the service execution request needs to consume a shorter time. This situation is unacceptable.

In order to solve the above problems, the related art proposes the following. And the terminal acquires the current count value of a counter in the bottom layer of the server through RDMA atomic operation provided by the RDMA network under the condition that the high layer of the server does not sense the current count value, and determines the current value of the counter as a mark updating sequence identifier. The terminal can still instruct the server to execute the target service through RDMA atomic operation. The terminal directly carries out RDMA atomic operation on the bottom layer of the server without the processing of the high layer of the server, so the execution efficiency of the RDMA atomic operation is high, the terminal can further quickly obtain the mark updating sequence mark and indicate the server to execute the target service, and the service execution progress mark in the bottom layer of the server can be updated according to the sequence indicated by the obtained mark updating sequence mark. For example, the terminal A, B, C has all instructed and determined that the server has executed the target service, and the flag update sequence flags allocated by the terminal A, B, C are sequentially 1, 2, and 3, then the terminal a updates the service execution progress flag first, and updates the service execution progress flag from the initial value 1 to 2. Only when the terminal B acquires that the current service execution progress mark is 2 after the terminal a finishes updating the service execution progress mark, the terminal B can update the service execution progress mark and update the service execution progress mark to 3. Only when the terminal C obtains that the current service execution progress mark is 3 after the terminal a and the terminal B finish updating the service execution progress mark, the terminal C can update the service execution progress mark and update the service execution progress mark to 4. If the terminal in the front of the sequence indicated by the flag updating sequence identifier does not update the service execution progress flag, the terminal in the back of the sequence indicated by the flag updating sequence identifier waits for the service execution progress flag to be updated.

In carrying out the present disclosure, the inventors found that at least the following problems exist:

the high-level server needs to check the current business execution progress mark at some moments, and determines the execution condition of the target business through the current business execution progress mark. When any terminal which indicates the server to execute the target service has an operation fault, other terminals cannot sense the fault, and therefore even if other terminals with the later sequence indicated by the mark updating sequence identifier indicate and determine that the server executes the target service, other terminals with the later sequence indicated by the mark updating sequence identifier cannot update the service execution progress mark, and the execution condition of the target service determined by the server high layer through the current service execution progress mark is not consistent with the actual execution condition.

Disclosure of Invention

In order to overcome the problems in the related art, the present disclosure provides the following technical solutions:

according to a first aspect of the embodiments of the present disclosure, there is provided a method of executing a service, the method including:

instructing the server to perform a target service by a remote direct data access, RDMA, atomic operation;

after the target service is determined to be executed by the server, determining at least one detection time point for acquiring a service execution progress mark from the server according to a preset detection time point determination rule;

and when any detection time point is reached, acquiring the service execution progress mark from the server through RDMA atomic operation, determining the time length of the service execution progress mark which is not updated, and carrying out carry updating on the service execution progress mark through RDMA atomic operation if the time length of the service execution progress mark which is not updated is greater than or equal to a preset time length threshold.

By the method provided by the embodiment of the disclosure, when any terminal indicating the server to execute the target service has an operation fault, other terminals can acquire the service execution progress mark from the server, determine the time length of the service execution progress mark which is not updated, and if the time length of the service execution progress mark which is not updated is greater than the preset time length threshold, it indicates that the terminal indicating the server to execute the target service has the operation fault, and then other terminals can automatically update the service execution progress mark. Therefore, even if a terminal with operation failure exists, other terminals with the later sequence indicated by the mark updating sequence identification can continuously update the service execution progress mark. When the server high level determines the execution condition of the target service through the current service execution progress mark, the determined execution condition of the target service can be consistent with the actual execution condition.

In one possible implementation, the target service is a service that writes log data in a target log, and the instructing the server to execute the target service through an RDMA atomic operation includes:

acquiring a data writing position corresponding to the target log from a server through RDMA atomic operation, and indicating the server to write log data in the data writing position;

after the target service is determined to be executed by the server, determining at least one detection time point for acquiring a service execution progress mark from the server according to a preset detection time point determination rule, including:

after the server is determined to write the log data in the data writing position, determining at least one detection time point for acquiring a writing position mark from the server according to a preset detection time point determination rule;

when any detection time point is reached, the service execution progress mark is obtained from the server through RDMA atomic operation, the time length of the service execution progress mark which is not updated is determined, if the time length of the service execution progress mark which is not updated is greater than or equal to a preset time length threshold value, the service execution progress mark is carried out carry updating through the RDMA atomic operation, and the method comprises the following steps:

and when any detection time point is reached, acquiring the writing position mark from the server through RDMA atomic operation, determining the time length of the acquired writing position mark which is not updated, and if the time length of the acquired writing position mark which is not updated is greater than or equal to a preset time length threshold value, carrying out carry updating on the writing position mark through the RDMA atomic operation.

In one possible implementation manner, the performing carry update on the service execution progress flag through an RDMA atomic operation includes:

through RDMA atomic operation, the server is instructed to compare a current service execution progress mark with a service execution progress mark of which the non-updated time length is greater than or equal to a preset time length threshold value;

if the current service execution progress mark is matched with the service execution progress mark of which the non-updated duration is greater than or equal to a preset duration threshold, instructing the server to increase the current service execution progress mark by a first preset value through RDMA atomic operation;

and if the current service execution progress mark is not matched with the service execution progress mark of which the non-updated duration is greater than or equal to the preset duration threshold, indicating the server to keep the current service execution progress mark unchanged through RDMA atomic operation.

By the mode, even if a plurality of terminals find that carry updating needs to be carried out on the service execution progress mark at the same time, the carry updating is carried out on the progress mark only once, and the situation that different terminals carry updating on the service execution progress mark for many times is avoided.

In one possible implementation, before instructing the server to execute the target service, the method further includes:

and acquiring a mark updating sequence identifier from the server through RDMA atomic operation.

In a possible implementation manner, after determining that the server has completed executing the target service, determining, according to a preset detection time point determination rule, at least one detection time point at which a service execution progress flag is obtained from the server, includes:

after the target service is determined to be executed by the server, acquiring a service execution progress mark from the server;

determining a difference value between the service execution progress mark and the mark updating sequence mark;

and determining at least one detection time point for acquiring the service execution progress mark from the server according to the difference.

By the method, the times that the terminal acquires the service execution progress mark from the server can be reduced, the working pressure of the server is relieved, and the operating efficiency of the server is improved.

In a possible implementation manner, after obtaining the service execution progress flag from the server, the method further includes:

comparing the service execution progress mark with the mark updating sequence mark;

and if the service execution progress mark is smaller than the mark updating sequence mark by a preset difference value, indicating the server to increase the service execution progress mark by a second preset numerical value.

and if the service execution progress mark is larger than or equal to the mark updating sequence mark, switching to a step of executing RDMA atomic operation to instruct the server to execute the target service.

Some target terminals which are found not to indicate the server to carry out carry updating on the service execution progress mark beyond the preset time length threshold value do not necessarily have operation faults. The target terminal may be that the processor is busy at the time when the server should be instructed to carry out carry updating on the service execution progress mark, and no time is instructed to carry updating on the service execution progress mark by the server. When the processor of the target terminal is in an idle time, the target terminal acquires a service execution progress mark from the server, compares the acquired service execution progress mark with a mark updating sequence mark acquired in advance, and because the service execution progress mark is automatically indicated by other terminals and the server carries out carry updating on the service execution progress mark, the service execution progress mark acquired by the target terminal is larger than or equal to the mark updating sequence mark acquired in advance. The target terminal cannot successfully update the service execution progress mark, at this time, the target terminal may obtain the mark update sequence mark from the server again, instruct the server to execute the target service again, and repeatedly execute all the processes in the embodiment of the present disclosure until the server can be successfully instructed to execute the target service and the service execution progress mark is successfully updated.

In a possible implementation manner, the preset time threshold is a preset multiple of the time required by the server to execute the target service once.

These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The embodiment of the disclosure provides a method for executing a service, which can be implemented by a terminal and implemented by matching a plurality of other terminals and a server. The terminal can be a mobile phone, a desktop computer, a notebook computer, etc. Fig. 1 is a schematic structural diagram of a system for executing a service according to an embodiment of the present disclosure. The system may include a terminal, a plurality of other terminals, and a server. The devices belong to RDMA network devices, and the terminals can directly operate data in the memory of the bottom layer of the server through RDMA atomic operation (the RDMA atomic operation is a unilateral operation) without perception of the high layer of the server.

The high-level server needs to check the current business execution progress mark at some moments, and determines the execution condition of the target business through the current business execution progress mark. When any terminal indicating the server to execute the target service has an operation fault, the terminals except the terminal cannot sense the fault. If the terminal with the later sequence indicated by the mark updating sequence identifier indicates and determines that the server completes the execution of the target service, the terminal with the later sequence indicated by the mark updating sequence identifier needs to update the service execution progress mark urgently, so that when the server determines the execution condition of the target service through the current service execution progress mark, the determined execution condition of the target service is consistent with the actual execution condition.

An exemplary embodiment of the present disclosure provides a method for executing a service, and as shown in fig. 2, a processing flow of the method may include the following steps:

step S210, instructing the server to execute the target service through RDMA atomic operation.

In implementation, the terminal can instruct the bottom server layer to execute the target service through an RDMA atomic operation, and the high server layer does not sense the operation in the process of executing the target service. The target service may be a service for writing log data in the target log, or may be other executable transactions.

Before the terminal needs the server to execute the target service, the terminal can acquire the mark updating sequence identifier from the server through RDMA atomic operation, and after the mark updating sequence identifier is taken, the terminal can instruct the server to execute the target service. If a plurality of terminals simultaneously need the server to execute the target service, the plurality of terminals may sequentially acquire the tag update sequence identifier from the server through RDMA atomic operation, and after the tag update sequence identifier is received, the plurality of terminals may simultaneously instruct the server to execute the target service, for example, the plurality of terminals include the terminal A, B, C, after the terminal A, B, C sequentially acquires the tag

update sequence identifiers

1, 2, and 3, the plurality of terminals may simultaneously instruct the server to execute the target service, and the server may concurrently execute the target service instructed by the plurality of terminals.

Step S220, after determining that the server has finished executing the target service, determining at least one detection time point for obtaining the service execution progress marker from the server according to a preset detection time point determination rule.

In the implementation, the terminal instructs the server to execute the target service, after the target service is determined to be executed by the server, the terminal needs to query the service execution progress mark in the server, and if the queried service execution progress mark is the same as the mark update sequence identifier obtained by the terminal, the terminal can carry out carry update on the service execution progress mark. In the above process, the terminal needs to query the service execution progress mark in the server, the terminal may determine a detection time point for subsequently acquiring the service execution progress mark from the server according to a preset detection time point determination rule, and when the detection time point is reached, the terminal may query the service execution progress mark in the server once. The detection time point may be one or more.

After the terminal determines that the server finishes executing the target service, the terminal can query the service execution progress mark in the server, and determine a detection time point for querying the service execution progress mark in the server next time based on the queried service execution progress mark. When the determined detection time point is reached, the terminal can query the service execution progress mark in the server again, and based on the queried service execution progress mark, the detection time point of the service execution progress mark in the server is determined again. The terminal may repeatedly execute the above operations until the queried service execution progress marker is the same as the marker update sequence identifier obtained by the terminal, which indicates that the terminal may carry out carry update on the service execution progress marker, and the terminal may stop continuously querying the service execution progress marker in the server.

And step S230, when any detection time point is reached, acquiring a service execution progress mark from the server through RDMA atomic operation, determining the time length of the service execution progress mark which is not updated, and if the time length of the service execution progress mark which is not updated is greater than or equal to a preset time length threshold value, carrying out carry updating on the service execution progress mark through RDMA atomic operation.

In implementation, the terminal may determine at least one detection time point for obtaining the service execution progress indicator from the server according to a preset detection time point determination rule, and the terminal may obtain the service execution progress indicator from the server through an RDMA atomic operation whenever any detection time point is reached. Where the RDMA atomic operation may be an RDMA Read operation. The service execution progress flag may be a count value in a counter, and may be represented by a sequence generator, an Identity (ID) generator, a logic clock, a count value of a distributed lock, and the like, in addition to the service execution progress flag being represented by the count value of the counter.

Terminal deviceAfter querying the service execution progress mark in the server each time, the service execution progress mark may be stored, and the corresponding detection time point may be recorded. After the terminal queries the service execution progress mark in the server again, the currently queried service execution progress mark may be compared with the previously queried service execution progress mark, and if the currently queried service execution progress mark is consistent with the previously queried service execution progress mark, it indicates that the currently queried service execution progress mark has not been updated for a period of time, and the terminal may determine a difference between a detection time point of the service execution progress mark which is not updated by the first query and a detection time point of the service execution progress mark which is not updated by the current query, as a duration for which the service execution progress mark is not updated. The terminal can judge whether the time length of the service execution progress mark which is not updated is greater than or equal to a preset time length threshold value, if the time length of the service execution progress mark which is not updated is greater than or equal to the preset time length threshold value, it is indicated that one other terminal in the plurality of terminals has an operation fault in the process of indicating the server to execute the target service, and at the moment, the terminal which detects the fault can automatically carry out carry updating on the service execution progress mark through RDMA atomic operation. Wherein the RDMA atomic operation may be RDMA CAS (N)_p，N_p+1) operation, N_pAnd N_p+1 is a parameter that the operation requires to be passed in.

Optionally, the server with the preset time threshold as a preset multiple needs to execute the target service once.

In implementation, the time length required for the server to execute the target service once is set to T, which may also be referred to as a lease time, and the preset time length threshold may be a preset multiple of T. The preset multiple may be set to 2, and the preset duration threshold may be 2T, that is, 2 lease times. The preset time length threshold value can be set according to actual requirements, or the multiple can be set.

Optionally, before instructing the server to execute the target service, the method provided by the embodiment of the present disclosure may further include: and acquiring a mark updating sequence identifier from the server through an RDMA atomic operation.

In an implementation, when the target transaction is a transaction that writes log data in the target log, the flag update sequence identifier may be the same value as the data write location, i.e., at what data write location the log data is written, in what sequence the transaction execution progress flag is updated.

Optionally, when the target service is a service for writing log data in the target log, the method provided by the embodiment of the present disclosure may include: acquiring a data writing position corresponding to a target log from a server through RDMA atomic operation, and indicating the server to write log data in the data writing position; after determining that the server writes log data in the data writing position, determining at least one detection time point for acquiring a writing position mark from the server according to a preset detection time point determination rule; and when any detection time point is reached, acquiring a writing position mark from the server through RDMA atomic operation, determining the time length of the acquired writing position mark which is not updated, and if the time length of the acquired writing position mark which is not updated is greater than a preset time length threshold value, carrying out carry updating on the writing position mark through the RDMA atomic operation.

In implementation, as shown in fig. 3, a Counter may be set in the server, and the Counter may be referred to as a Counter, and the Counter may include two parts, a first part is Nprocessing and a second part is Nincoming. The total data size of the count value of the counter may be 64 bits, Nprocessing may account for 32 bits, and Nincoming may account for 32 bits. The Nprocessing count may represent the sequence number currently being processed (also referred to as a write location tag), and the Nincoding count may represent the number that the next terminal to obtain the tag update sequence identifier from the server can take (also referred to as a data write location). Of course, the total data amount of the count value of the counter may also be set to other values, and the embodiment of the present disclosure is not limited thereto.

The system for executing the service may include a terminal and a Server, where the terminal may also be referred to as a Client side and the Server may also be referred to as a Server side. As shown in fig. 4, the Client and the Server are disposed in the RDMA network, the Client and the Server are respectively installed with an RDMA driver, and the Server is also installed with a Memory (Memory), which is an operation object of RDMA atomic operation. In practical application, a plurality of Client terminals and a plurality of Server terminals may be arranged in an RDMA network, in the embodiment of the present disclosure, the working mechanisms of one Client terminal and one Server terminal are taken as an example for description, and the working mechanisms of other Client terminals and other Server terminals are similar to them, and a description thereof is not repeated.

The Client side can instruct the Server side to execute a specific operation through RDMA atomic operation. In the disclosed embodiments, 3 RDMA atomic operations are primarily involved, including RDMA Fetch-and-Add (N)_i) Operation, which may be denoted as RDMA FAA (N)_i) (ii) a RDMA Read operation, which may be denoted RDMA Read; RDMA Fetch-and-Add (N)_p) Operation, denoted RDMA FAA (N)_p)。

When the Client needs to write log data into the Server, as shown in fig. 5, the Client can pass through RDMA FAA (N)_i) The count value of the Nincoming in the Server end is obtained, and meanwhile, the count value of the Nincoming in the Server end can be added with 1. As shown in fig. 6, when the detection time point is reached, the Client may obtain the Nprocessing count value and the Nincoming count value in the Server via RDMA Read. As shown in fig. 7, when the count value of Nprocessing queried by the Client is the same as the count value of nincoding acquired by the Client, it indicates that the Client can carry out carry update on Nprocessing in the Server, and at this time, the Client can perform carry update on Nprocessing in the Server through RDMA FAA (N)_p) The count value of Nprocessing in the Server end is obtained, and meanwhile, the count value of Nprocessing in the Server end can be increased by 1. When the count value of the Nprocessing queried by the Client is smaller than the count value of the nincoding acquired by the Client by N (N is greater than or equal to 1), the Client may record the count value of the Nprocessing queried currently. When the detection time point is reached again, the Client terminal can query the Nprocessing count value again, and if the queried Nprocessing count value is not updated compared with the queried Nprocessing count value, and the updating time length is greater than the preset time length threshold value, the RDMA CAS (N-RDMA CAS) is passed through (N is a maximum allowable resource locator)_p，N_p+1) operation, automatically executing on the serviceThe progress mark carries out carry updating.

Optionally, the step of carrying out carry update on the service execution progress flag through an RDMA atomic operation may include: through RDMA atomic operation, indicating a server to compare a current service execution progress mark with a service execution progress mark of which the non-updated time length is greater than a preset time length threshold value; if the current service execution progress mark is matched with the service execution progress mark of which the non-updated duration is greater than the preset duration threshold, indicating the server to increase the current service execution progress mark by a first preset value through RDMA atomic operation; and if the current service execution progress mark is not matched with the service execution progress mark of which the time length without updating is greater than the preset time length threshold, indicating the server to keep the current service execution progress mark unchanged through RDMA atomic operation.

In implementation, the terminal may pass through RDMA CAS (N)_p，N_pAnd +1), automatically carrying out carry updating on the service execution progress mark. Wherein N is_pAnd N_p+1 is the parameter that the operation needs to be passed in, N_pFor the service requiring carry updating, N_p+1 is the service execution progress mark after carry updating, and N can be set_p+1 set to the ratio N_pA value greater than 1. Thus, the terminal can pass through RDMA CAS (N)_p，N_p+1) operation, instructing the server to compare the current business execution progress mark with N_pIf the current service execution progress flag and N_pIf the indication is valid, the current service execution progress mark can be replaced by N_p+1。

If the terminal finds that the service execution progress marker needs to be carried out carry updating while other terminals find that the service execution progress marker needs to be carried out carry updating through the method provided by the embodiment of the disclosure, the server may receive the indication of carrying out carry updating on the service execution progress marker twice or more. At this time, the server performs carry updating on the service execution progress mark according to the indication of performing carry updating on the service execution progress mark received at the first time. On-pair serviceAfter the execution progress mark carries out carry updating, if an indication for carrying out carry updating on the service execution progress mark is received later, a parameter N carried in the indication_pThe server compares the current business execution progress mark with the server, so that the description indication is invalid, and the server keeps the current business execution progress mark unchanged.

Optionally, after determining that the server has completed executing the target service, according to a preset detection time point determination rule, the step of determining at least one detection time point for obtaining the service execution progress marker from the server may include: after the server is determined to finish executing the target service, acquiring a service execution progress mark from the server; determining a difference value between the service execution progress mark and the mark updating sequence mark; and determining at least one detection time point for acquiring the service execution progress mark from the server according to the difference.

In implementation, the terminal may determine at least one detection time point for obtaining the service execution progress indicator from the server, where a time interval of each time point is the same and is a preset value. Or, after determining that the server has completed executing the target service, the terminal may obtain a service execution progress marker from the server, determine a difference between the service execution progress marker and the marker update sequence identifier, and determine at least one detection time point at which the service execution progress marker is obtained from the server according to the difference.

After the server is determined to finish the target service, the terminal can timely acquire a service execution progress mark from the server for determining the number of the sequence numbers currently being processed, and meanwhile, the terminal can also determine a mark update sequence identifier acquired in advance for determining the number of the sequence numbers taken by the terminal. When the sequence number currently being processed is matched with the sequence number taken by the server, the server is indicated by the server to carry out carry updating on the service execution progress mark. If the sequence number currently being processed is different from the sequence number taken by the terminal, the terminal can wait for a period of time more and obtain the service execution progress mark from the server again. In practical application, the terminal may determine a difference between the service execution progress marker and the marker update sequence identifier, and determine a detection time point for obtaining the service execution progress marker from the server according to the difference.

For example, if the service execution progress flag is 1, the flag update sequence flag is 3, and the difference between them is 2, it indicates that two terminals in front need to instruct the server to carry out carry update on the service execution progress flag, and it turns to the current terminal to instruct the server to carry out carry update on the service execution progress flag. Assuming that the time length required by the server to execute the target service once is T, the current terminal may wait for the determined difference multiple T to obtain the service execution progress mark from the server again, that is, wait for 2T to obtain the service execution progress mark from the server again. In this way, when the terminal acquires the service execution progress mark from the server again, the acquired service execution progress mark should be the same as or closer to the mark update sequence identifier acquired in advance. The detection time point determined based on the difference may be taken as a first detection time point, a time point obtained by adding T to the first detection time point may be taken as a second detection time point, and a time point obtained by adding T to the second detection time point may be taken as a third detection time point. By analogy, when the first detection time point is determined, the time point obtained by adding T once to the first detection time point is used as one detection time point, and finally a plurality of detection time points can be obtained.

Or, the terminal may determine the first detection time point, obtain the service execution progress marker from the server after the first detection time point is reached, determine a difference between the service execution progress marker and the marker update sequence identifier, and determine the second detection time point at which the service execution progress marker is obtained from the server according to the difference. The terminal can repeatedly execute the steps of obtaining the service execution progress mark from the server when the determined detection time point is reached, determining the difference value between the service execution progress mark and the mark updating sequence mark, determining the detection time point of obtaining the service execution progress mark from the server according to the difference value, and stopping repeatedly executing the steps until the service execution progress mark obtained by the terminal is the same as the mark updating sequence mark obtained in advance by the terminal.

Optionally, after obtaining the service execution progress mark from the server, the method provided by the embodiment of the present disclosure may further include: comparing the service execution progress mark with the mark updating sequence mark; and if the service execution progress mark is matched with the mark updating sequence mark, indicating the server to increase the service execution progress mark by a second preset value.

In implementation, each time any detection time point is reached, the terminal may obtain a service execution progress marker from the server, compare the obtained service execution progress marker with a marker update sequence marker obtained in advance, indicate that the terminal indicates that the server updates the service execution progress marker by carrying out a carry in turn if the service execution progress marker is the same as the marker update sequence marker, and at this time, the terminal may indicate that the server increases the service execution progress marker by a second preset value (e.g., 1).

Optionally, after obtaining the service execution progress mark from the server, the method provided by the embodiment of the present disclosure may further include: and if the service execution progress mark is larger than or equal to the mark updating sequence mark, switching to the step of executing the RDMA atomic operation and indicating the server to execute the target service.

In implementation, some target terminals which are found not to indicate the server to carry out carry updating on the service execution progress flag beyond the preset time threshold do not necessarily have to be the operation fault. The target terminal may be that the processor is busy at the time when the server should be instructed to carry out carry updating on the service execution progress mark, and no time is instructed to carry updating on the service execution progress mark by the server. When the processor of the target terminal is in an idle time, the target terminal acquires a service execution progress mark from the server, compares the acquired service execution progress mark with a mark updating sequence mark acquired in advance, and because the service execution progress mark is automatically indicated by other terminals and the server carries out carry updating on the service execution progress mark, the service execution progress mark acquired by the target terminal is larger than or equal to the mark updating sequence mark acquired in advance. The target terminal cannot successfully update the service execution progress mark, at this time, the target terminal may obtain the mark update sequence mark from the server again, instruct the server to execute the target service again, and repeatedly execute all the processes in the embodiment of the present disclosure until the server can be successfully instructed to execute the target service and the service execution progress mark is successfully updated.

In an application scenario, when the target service is a service for writing log data in a target log, as shown in fig. 8, there are 3 terminals that need to write log data in the target log at the same time, and the 3 terminals include Client 1, Client 2, and Client 3. Before each Client writes log data, the server needs to acquire a data writing position from the server, so that different clients can respectively acquire different data writing positions, and the different clients can parallelly instruct the server to write the log data. In fig. 8, the Client and the Server interact with each other, as shown by the sequence numbers in parentheses in the connecting line in fig. 8, the sequence numbers from small to large indicate the sequence of the interactions, and the Client and the Server interact 7 times as shown by the sequence numbers, which includes:

(1) client 1 over RDMA FAA (N)_i) Operation, obtaining current N to server_iValue 1, data write location 1 is obtained.

(2) Client 2 over RDMA FAA (N)_i) Operation, obtaining current N to server_iValue 2, get data write location 2.

(3) Client3 over RDMA FAA (N)_i) Operation, obtaining current N to server_iValue 3, get data write location 3.

N is acquired by Client 1, Client 2, and Client3_iAnd after the data writing position, the server can be instructed to write the log data in the acquired data writing position in parallel.

(4) After Client 1 instructs the server to write the log data, Client 1 may go through RDMA FAA (N)_p) Operation release N_pRelease of N_pAlso called commit operation, N in server_pIn this case 2, N_iIn this case 3.

(5) Releasing N by Client 1_pLater, if the log data needs to be written again, it can go through RDMA FAA (N) again_i) Operation, obtaining current N to server_iValue 4, data write location 4 is obtained.

(6) Each Client, after determining that the server writes log data, is ready to perform a commit operation. At this time, each Client that determines that the server writes log data obtains the current N from the server_pTo determine whether it is time for the current Client to perform a commit operation. If any of the clients (e.g., Client3 in FIG. 8) finds after 2T, N_pIf no update is performed, the Client can determine that there is an operation failure of the target Client (e.g., Client 2 in fig. 8). At this time, Client3 may go through RDMA CAS (N)_p，N_p+1) operation, N in the server_pPlus 1. Optionally, the Client3 may also send a message indicating that the Client 2 has an operational failure to the server, indicating that the server Client 2 has an operational failure. At this time, Np in the server is 3, N_iIs 4.

(7) After Client3 determines that the server writes log data, it may go through RDMA FAA (N)_p) Operation release N_pN in the server_pIn this case 4, N_iThis time 4.

By the method provided by the embodiment of the disclosure, the mark update sequence identifier can be quickly acquired from the server through the RDMA atomic operation, and the problem that the state cannot be sensed because the RDMA atomic operation is a unilateral operation can be avoided. The method provided by the embodiment of the disclosure can be applied to a distributed shared log system, a distributed transaction system and the like.
