Background
The cloud platform generally adopts a distributed network architecture and is built by network elements on different servers. A specific service flow usually requires multiple network elements to be completed cooperatively.

And continuously accumulating the data of each network element from the initial network element participating in the business processing and transmitting the data to the next network element until the last network element participating in the business processing performs final persistence processing on the data. Although the processing scheme ensures the integrity and unification of the data, the processing complexity of each network element is increased, each network element needs to pay attention to not only the service logic of the network element, but also the data transmitted from the upstream and the data prepared to the downstream, and in addition, the accumulation of the data packets increases the burden of network transmission, which causes low processing capacity.

Detailed Description
The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In order to ensure the integrity and unification of data after transaction processing on the premise of not reducing processing performance, an embodiment of the present invention provides a transaction processing control method in a distributed network, and as shown in fig. 1, the method specifically includes:
step 100, allocating identification Information (ID) to the transaction to be processed, and sending the identification information to the network element that processes the transaction, so that after processing the transaction, the network elements at each level that process the transaction store the data obtained by processing the transaction by the network element in association with the identification information.
In an embodiment of the invention, the transaction is processed by a plurality of network elements in the distributed network. Then the identification information may be sent separately to all network elements that handle the transaction. Preferably, the identification information may also be sent only to the initial network element that processes the transaction, and then each network element sends the identification information to the next level network element after processing the single node transaction. The single-node transaction processing means that during the transaction processing, a single network element processes a part of transactions responsible for the node.
Step 110, monitoring the processing state of the transaction by reading the cache space for saving the state information of the transaction.
The specific implementation manner of monitoring the processing state of the transaction is related to the state information storage position of the transaction. And if the network element processing the transaction stores the state information of the transaction and the identification information in a shared cache space in a correlated manner, monitoring the state of the transaction by reading the shared cache space. If the state information of the transaction and the identification information are respectively stored in the corresponding cache spaces by the network elements of each level processing the transaction, the processing state of the transaction is monitored by reading the cache spaces corresponding to the network elements of each level.
The cache space where the state information of the transaction stored by each level of network element corresponds to the identification information may be the same or different.
And step 120, when the processing end state information corresponding to the identification information of the transaction is read, performing persistence processing on data corresponding to the identification information stored in each level of network element for processing the transaction.
The specific implementation mode of performing persistence processing on the data associated with the identification information stored by each level of network elements for processing the transaction is related to the position of data storage. If the data obtained by processing the transaction by the network elements at each level is stored in the shared cache space in association with the identification information, a specific implementation manner of performing persistence processing on the data associated with the identification information stored by the network elements at each level for processing the transaction may be: acquiring data associated with the identification information from the shared cache space; and carrying out persistence processing on the acquired data. If the data obtained by processing the transaction by the network elements at each level and the identification information are respectively associated and stored in the corresponding cache space, a specific implementation manner of performing persistence processing on the data associated with the identification information stored by the network elements at each level for processing the transaction may be: respectively obtaining data associated with the identification information from the cache space corresponding to the network elements at each level; and carrying out persistence processing on the acquired data.
The corresponding cache spaces for storing the data by the network elements at each level may be the same or different.
In addition, the state information of the transaction stored by each network element and the cache space corresponding to the data may be the same or different.
The method provided by the embodiment of the invention can uniformly manage the transaction processing process and uniformly process the data submitted by the network elements for processing the transaction, can ensure the completeness and uniformity of the data without transmitting the data by each network element, reduces the processing complexity of each network element and improves the processing capacity.
Preferably, the shared cache space includes a stack memory and a heap memory. If the network element processing the transaction stores the state information of the transaction and the identification information in a shared cache space in a correlated manner, the state information of the transaction and the identification information are stored in a stack memory of the shared cache space in a correlated manner. If the data obtained by processing the transaction by the network elements at all levels is stored in the shared cache space in association with the identification information, the data obtained by processing the transaction is stored in a heap memory of the shared cache space, and a pointer indicating the data storage position is stored in a stack memory in association with the identification information.
Because the processing capacity of the stack memory is strong, frequently called information (such as state information of transactions) can be cached in the stack memory, and therefore the performance of the shared cache module is improved.
In the prior art, if a network element is abnormal, the network element performs a transaction rollback operation. In the embodiment of the present invention, the abnormal network element only needs to store the abnormal data in association with the identification information, and store the information for processing the abnormal state. Correspondingly, based on any of the embodiments, if the data obtained by processing the transaction by the network elements at each level is stored in the shared cache space in association with the identification information, and before the processing end state information corresponding to the identification information of the transaction is read, the processing abnormal state information corresponding to the identification information of the transaction is read, the data associated with the identification information stored in the shared cache space is also subjected to rollback processing, wherein the abnormal network element stores the abnormal data in association with the identification information in the shared cache space. And if the data obtained by processing the transaction by the network elements at all levels and the identification information are respectively stored in the corresponding cache spaces in a correlated manner, and before the processing ending state information corresponding to the identification information of the transaction is read, the processing abnormal state information corresponding to the identification information of the transaction is read, and the data associated with the identification information stored in the cache spaces corresponding to the network elements at all levels is subjected to rollback processing, wherein the abnormal data and the identification information are stored in the corresponding storage spaces in a correlated manner by the abnormal network elements.
So-called rollback, i.e. deleting the corresponding data (including the data obtained by completing the processing and the abnormal data). In the rollback processing in the embodiment of the present invention, all the data corresponding to the reported identification information is deleted. Therefore, after the rollback processing is performed, the transaction processing flow is finished.
In the method provided by the embodiment of the invention, when a certain network element generates abnormal data, the transaction management device uniformly rolls back the data submitted by the network element which has finished processing, so that the generation of dirty data can be avoided.
Based on the same inventive concept as the method, an embodiment of the present invention further provides a transaction control device in a distributed network, as shown in fig. 2, the transaction control device in the distributed network includes:
the registration module 201 is configured to allocate identification information to a transaction to be processed, and send the identification information to a network element that processes the transaction, so that after processing the transaction, each level of network elements that process the transaction store data obtained by processing the transaction by the network element in association with the identification information.
In the embodiment of the present invention, preferably, the registration module 201 registers the transaction to be processed, and performs unified processing and scheduling management on the rules, objects, and resources of the transaction management. Here, registration is to allocate not only identification information to a transaction to be processed, but also to initialize a thread for the transaction and allocate a shared cache space to the transaction.
In addition, after allocating the identification information to the transaction to be processed, the registration module 201 also sends the identification information to the monitoring module 202, and notifies the monitoring module 202 to monitor the processing state of the transaction corresponding to the identification information.
The monitoring module 202 is configured to monitor a processing state of the transaction by reading a cache space for storing state information of the transaction.
Specifically, after receiving the notification from the registration module 201, the monitoring module 202 monitors the processing state of the transaction corresponding to the identification information.
The monitoring of the processing state of the transaction by reading the cache space for storing the state information of the transaction specifically means reading the cache space to obtain the state information of the transaction, and monitoring the processing state of the transaction according to the obtained state information of the transaction.
The processing module 203 performs persistence processing on the data associated with the identification information stored in each level of network element that processes the transaction when the monitoring module 202 reads the processing end state information corresponding to the identification information of the transaction.
Specifically, when the monitoring module 202 reads the processing end state information corresponding to the identification information of the transaction (i.e., monitors the processing end state of the transaction), it notifies the processing module 203 to perform the persistence processing. Correspondingly, the processing module 203 performs persistence processing on the data corresponding to the identification information submitted by the network element that processes the transaction according to the notification.
The device provided by the embodiment of the invention can uniformly manage the transaction processing process and uniformly process the data submitted by the network elements for processing the transaction, can ensure the completeness and uniformity of the data without transmitting the data by each network element, reduces the processing complexity of each network element and improves the processing capacity.
In the embodiment of the present invention, the monitoring module 202 and the processing module 203 may be implemented by threads, specifically, by using a multi-thread polling method. Taking the monitoring module 202 as an example, assuming that one thread for monitoring corresponds to one transaction, each thread for monitoring corresponds to two states, active and dormant. The threads in the activated state occupy more resources, the threads in the dormant state release part of the resources, and each thread in the monitoring thread pool adopts a polling mode to ensure that all the threads for monitoring can be switched in a balanced state so as to monitor the processing states of all the transactions, thereby ensuring the maximum bearing of the processing capacity of the monitoring threads during high concurrency. The initialization of the monitoring thread pool and the control of the polling mode are realized by the registration module 201.
Based on any of the above embodiments, a preferred implementation of each of the above modules is described below. It should be noted that these preferred implementations can be used alone or in combination.
Since the apparatus provided by the embodiment of the present invention gives the same inventive concept as the above method, repeated descriptions will be omitted.
When the identifier information is sent to the network element that processes the transaction, the registration module 201 may be specifically configured to: sending the identification information to an initial network element for processing the transaction, wherein the identification information is transmitted stage by stage between network elements for processing the transaction in the transaction processing process; or sending the identification information to network elements at each level for processing the transaction.
If the network element that processes the transaction stores the state information of the transaction in the shared cache space in association with the identification information, the monitoring module 202 may be specifically configured to: monitoring the state of the transaction by reading the shared cache space;
if the network elements at each level that process the transaction respectively store the status information of the transaction and the identification information in corresponding cache spaces, the monitoring module 202 may be specifically configured to: and monitoring the processing state of the transaction by reading the cache space corresponding to the network elements at each level.
If the data obtained by processing the transaction by the network elements at each level is stored in the shared cache space in association with the identification information, the processing module 203 may be specifically configured to: acquiring data associated with the identification information from the shared cache space; carrying out persistence processing on the acquired data;
if the data obtained by processing the transaction by the network elements at each level and the identification information are respectively stored in a corresponding cache space in a related manner, the processing module 203 may be specifically configured to: respectively obtaining data associated with the identification information from the cache space corresponding to the network elements at each level; and carrying out persistence processing on the acquired data.
Preferably, as shown in fig. 3, the apparatus provided in the embodiment of the present invention may further include a shared cache module 204, where the shared cache module 204 is the above-mentioned shared cache space. Further, the shared cache module 204 includes a stack memory and a heap memory. If the network element processing the transaction stores the state information of the transaction in the shared cache module 204 in association with the identification information, the state information of the transaction is stored in the stack memory of the shared cache module 204 in association with the identification information. If the data obtained by processing the transaction by the network elements at each level is stored in the shared cache module 204 in association with the identification information, the data obtained by processing the transaction is stored in the heap memory of the shared cache module 204, and the pointer indicating the data storage location is stored in the stack memory in association with the identification information.
Because the processing capacity of the stack memory is strong, frequently called information (such as state information of transactions) can be cached in the stack memory, and therefore the performance of the shared cache module is improved.
If the data obtained by processing the transaction by the network elements at each level is stored in the shared cache space in association with the identification information, and before the processing end state information corresponding to the identification information of the transaction is read, the monitoring module 202 reads the processing abnormal state information corresponding to the identification information of the transaction, the processing module 203 may be further configured to: rolling back the data associated with the identification information stored in the shared cache space; if the data obtained by processing the transaction by the network elements at each level and the identification information are respectively stored in the corresponding cache space in a correlated manner, and before the processing end state information corresponding to the identification information of the transaction is read, the monitoring module 202 reads the processing abnormal state information corresponding to the identification information of the transaction, the processing module 203 may be further configured to: and performing rollback processing on the data associated with the identification information stored in the cache space corresponding to the network elements at each level.
Based on the same inventive concept as the method, an embodiment of the present invention further provides a network element in a distributed network, as shown in fig. 4, including:
an identification information receiving module 401, configured to receive identification information of a transaction to be processed;
a transaction processing module 402, configured to process the transaction;
a data saving module 403, configured to store the data obtained by processing the transaction by the network element in association with the identifier information.
The network element provided by the embodiment of the invention does not need to transmit the data obtained by processing the transaction, only needs to store the data obtained by processing the transaction by the network element in association with the identification information, and carries out unified management on the transaction processing process by the transaction processing control device and unified processing on the data submitted by the network element for processing the transaction, thereby reducing the processing complexity of each network element and improving the processing capability.
Preferably, the identification information receiving module 401 is specifically configured to:
receiving identification information of the transaction sent by a transaction control device, wherein the identification information is distributed by the transaction control device; or,
and receiving the identification information of the transaction, which is sent by the upper-level network element for processing the transaction, wherein the identification information is distributed by the transaction processing control device and is sent to the initial network element for processing the transaction.
The method provided by the embodiment of the present invention will be described in detail below by taking the network element shown in the transaction control device shown in fig. 3 as an example.
When the flow of the transaction process is started, the registration module 201 of the transaction process control apparatus registers the transaction. Specifically, the identification information is allocated to the transaction, the thread of the monitoring module 202 and the thread of the processing module 203 are initialized for the transaction, and the shared cache space (i.e., the shared cache module 204) is allocated for the transaction.
The registration module 201 sends the identification information to the initial network element that processed the transaction.
The initial network element receives the identification information; processing the part of the transaction which is handled by the local network element; after the processing is completed, the data to be persisted and the identification information obtained by the processing are stored in the shared cache module 204 of the transaction processing control device in an associated manner, and the identification information is sent to the next-level network element.
The next-level network element processes the part of the transaction which is responsible for processing, stores the data which is obtained by processing and needs to be persisted and the identification information into the shared cache module 204 of the transaction processing control device in a correlation manner, and sends the identification information to the next-level network element.
The above steps are repeated until the last level network element processing the transaction, and after the last level network element processes the part of the transaction which is responsible for processing the transaction, the last level network element stores the transaction processing end state information in the shared cache module 204 in addition to the data needing to be persisted according to the above manner.
For any level network element processing the transaction, once an exception occurs when the transaction is processed, the exception data and the identification information are stored in the shared cache module 204 of the transaction processing control device in an associated manner, and transaction processing exception state information is also stored in the shared cache module 204. At this time, the network element finishes the transaction processing flow, and there is no processing action of the subsequent network element.
The specific implementation manner of storing the data to be persisted or the abnormal data and the identification information in the shared cache module 204 in an associated manner may be: judging whether the stack memory of the shared cache module stores the identification information of the transaction, if not, storing the data needing to be persisted in the stack memory of the shared cache module, and storing the identification information and the pointer of the address of the data needing to be persisted in the stack memory in a correlated manner.
Optionally, for the non-last-level network element, after the partial processing of the transaction in charge of the local network element is completed, single-node transaction processing completion state information may also be generated and stored in the shared cache module 204.
The specific implementation manner of storing the processing state information of the transaction (transaction ending state information, transaction exception state information, and single-node transaction completion state information) in the shared cache module 204 may be: and storing the state information and the identification information in a stack memory in a related manner.
In the monitoring module 202, when the thread corresponding to the transaction is in an active state, the stack memory of the shared cache module 204 is continuously read to monitor the state of the transaction. If the transaction processing abnormal state information is read, the processing module 203 is triggered to perform rollback operation, and if the transaction processing ending state information is read, the processing module 203 is triggered to perform persistence operation.
If the rollback operation needs to be performed, the processing module 203 reads all the data corresponding to the above identification information in the heap memory of the shared cache module 204, and deletes the data.
