Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The flow provided by the embodiment of the application is applied to a remote double-activity system and is used for effectively shunting the service to the systems in different areas.
In the practical application process of service diversion, the applicant finds that:
because the security trust levels of the systems in the two regions are different, for example, the remote system is a newly built system, the security trust level is lower, the local system is a system which is used for a long time, and the security trust level is higher, so that in order to consider the security trust and ensure the processing efficiency and stability of the service, in the initial stage of deployment of the remote system, only a small amount of service is usually split, i.e. the service with a small amount is switched to the remote system for execution, so as to verify whether the remote system has the capability of bearing service split. In the process of initiating a service, a service initiating device (such as a pos machine) or a service initiating merchant (such as a local merchant) is generally used as a service initiator. For service initiation devices, the number of service initiation is small, and one service initiation device typically initiates only one service within a limited time. For the service initiating merchant, because the service initiating merchant comprises a large number of service initiating devices, compared with the service initiating device, the service initiating merchant is taken as a service initiating party, and the number of the initiated services is large.
Therefore, for the distribution of a small number of services, the distribution of a small number of services to a remote system by taking one service as a distribution dimension can be realized according to the distribution mode of the equipment number (i.e. the number of the service initiating equipment, such as the number of the pos machine: 0123). For example, 100 service initiation devices, each service initiation device initiates two services within one hour. And carrying out service initiation for 2 hours in total, sending out 400 parts of service, selecting a small amount of service (for example, 50 parts) from 400 parts of service, distributing 50 parts of service to a different-place system according to a device number distribution mode, and distributing the rest 120 parts to a local system.
After the distribution verification of a small amount of services is passed, the fact that the remote system has the capacity of bearing service distribution is determined, and then the distribution of a large amount of services to the remote system by taking a service set as a distribution dimension can be realized according to a distribution mode of an organization number (a code of a region where a service initiating merchant belongs, for example, 102000-Anhui). For example, 10 service initiating merchants, each service initiating merchant initiates 1000 services within one hour, and initiates 10000 services within 1 hour in total, and the local system and the remote system each bear 5000 services, so that 5000 services are distributed to the local system and 5000 services are distributed to the remote system according to the mode of mechanism number distribution.
In addition, whether the local system or the remote system, the database shards for storing the service message (typically, the service initiator will send the service message to the local system or the remote system during the process of initiating the service) may not be used for individual reasons. In the operation and maintenance process of the remote double-activity system, aiming at the situation that the database fragments in the remote system cannot be used, service messages stored in the fault database fragments can be switched to the local system for processing in a fragment number splitting mode. Of course, when the local system fails, the service message stored in the local system can be sent to the remote system in a splitting number splitting mode. In addition, in order to realize the operation and maintenance requirements under the condition that the database fragments in the local system or the remote system have no faults, the service messages stored in the database fragments of any one system can be sent to the other system in a split number splitting mode. For example, the remote system adopts a mysql database, a certain database fragment of the mysql database cannot be used, and in the process of operating and maintaining the remote system, the service message stored under the fault mysql database fragment is sent to the local system, so that the local system can bear the service to which the service message belongs, the loss of the service is avoided, and the reliability of operation and maintenance is improved.
Based on the findings of the applicant, the embodiments of the present application provide the following technical solutions: fig. 1 is a schematic diagram of a service splitting method according to an embodiment of the present application, and in the method shown in fig. 1, a transaction service is taken as an example for explanation.
The flow shown in fig. 1 may be executed by a server, specifically, the server receives a transaction message sent by a service initiator, and determines, according to configuration information stored in a distributed cache, a sending object of the transaction message, where in this embodiment, fig. 1 includes the following steps:
s101: and acquiring a transaction message.
S102: unpacking the transaction message to obtain the equipment number and the organization number.
The transaction message includes a device number and an organization number, and the specific implementation process of the device number and the organization number is obtained by unpacking the transaction message, which is known to those skilled in the art, and is not described herein.
S103: and reading a preset distributed cache, and judging whether the distributed cache has configuration information of the equipment number. If the configuration information of the device number exists in the distributed cache, S104 is executed, otherwise S105 is executed.
The configuration information of the device number includes a first Key-Value pair (Key-Value), where the first Key-Value pair is used to indicate a correspondence between the device number and a cluster name, and the cluster name is a cluster name of a local system or a remote system (for example, the cluster name of the local system is a Shanghai-nan cluster, and the cluster name of the remote system is a Wuhan-nan cluster).
It should be noted that, a cluster is a technology commonly adopted in the existing service system, and a cluster is a group of mutually independent computers interconnected through a high-speed network, where the computers form a group and are managed in a mode of a single system (i.e., a local system or a remote system), and the cluster is just like an independent server (i.e., a server to which the local system or the remote system belongs).
Specifically, the data format of the first key-value pair includes:
key = device number: value = cluster name.
The pair "abcdefgh" is represented by the first key value: "whSouthGroup" is taken as an example, the first bond value represents: device no abcdefgh: the Wuhan south cluster.
It should be noted that the distributed cache mentioned in this embodiment includes, but is not limited to, a hazelcast cache. The hazelcast cache adopts an embedded deployment mode, and each cache node is equal to each other, so that the cache invalidation problem caused by the fault of a single cache node can be avoided, and the consistency of cache data can be effectively ensured.
S104: and sending the transaction message to a local system or a remote system according to the corresponding relation indicated by the first key value pair.
The pair "abcdefgh" is represented by the first key value: "whSouthGroup" and "abd": for example, "shSouthGroup" indicates the correspondence between the device number abcdefgh and the south-martial-China cluster, and between the device number abd and the south-martial-China cluster, which belongs to a different-place system, and the south-martial-China cluster which belongs to a local system, so that the transaction message of the device number abcdefgh is sent to the different-place system. And sending the transaction message of the equipment number abd to a local system.
Obviously, according to the corresponding relation indicated by the first key value pair, the sending object of the transaction message is determined, so that a small number of businesses can be distributed to a different-place system by taking one business as a distribution dimension, in other words, the businesses can be distributed to the different-place system in a mode of distributing equipment numbers.
S105: and judging whether the configuration information of the organization number exists in the distributed cache. If there is configuration information of the organization number in the distributed cache, S106 is executed, otherwise S107 is executed.
The configuration information of the mechanism number comprises a second key value pair, and the second key value pair is used for indicating the corresponding relation between the mechanism number and the cluster name.
Specifically, the data format of the second key-value pair includes:
key = mechanism number: value = cluster name.
The second key value pair "101600": "shSouthGroup" is taken as an example, the second bond value pair represents: mechanism number 101600: and E, a Shanghai square cluster.
S106: and sending the transaction message to a local system or a remote system according to the corresponding relation indicated by the second key value pair.
With the second key value pair "101": "whSouthGroup" and "101600": for example, "shSouthGroup", the second key pair indicates the correspondence between the organization number 101 and the south-martial-China cluster, and between the organization number 101600 and the south-above-sea cluster, which belongs to a remote system, and the south-above-sea cluster belongs to a local system. And, the number of transaction messages with the organization number of 101 is 1000 parts, and the number of transaction messages with the organization number of 101600 is 1000 parts. Thus, 1000 transaction messages of the organization number 101 are sent to the off-site system. 1000 transaction messages of the organization number 101600 are sent to the local system.
Obviously, according to the corresponding relation indicated by the second key value pair, the sending object of the transaction message is determined, so that the service set is taken as the diversion dimension, and more services can be diverted to the different-place system, in other words, the service can be diverted to the different-place system according to the equipment number diversion mode.
S107: and sending the transaction message to a local system.
The distributed cache has no configuration information of the equipment number and the mechanism number, so that only the transaction message can be sent to the local system, i.e. service distribution is not performed.
S108: under the condition that the database fragments of the remote system are faulty, the target transaction message is obtained from the remote system, and the fragment number of the database fragment to which the target transaction message belongs is calculated through the equipment number obtained by unpacking the target transaction message.
The target transaction message is a transaction message stored in a fault database in a sliced manner, and the specific implementation process of calculating the slicing number of the database in which the target transaction message belongs through the equipment number of the target transaction message can be seen in the following steps and explanation of the steps shown in fig. 2.
Optionally, when the database fragment of the local system fails, a transaction message stored in the failed database fragment is obtained from the local system, and the fragment number of the database fragment to which the transaction message belongs is calculated through the equipment number obtained by unpacking the transaction message.
S109: and changing the configuration information of the fragment numbers pre-stored in the distributed cache, so that the changed configuration information indicates the corresponding relation between the fragment numbers and the local system.
The configuration information of the fragment number comprises a third key value pair, wherein the third key value pair is used for indicating the corresponding relation between the fragment number and a preset numerical value, and the preset numerical value indicates 0 or 1.
When the preset value indicates 0, the target transaction message stored in the database fragment to which the fragment number belongs in the remote system is sent to the local system. When the preset value indicates 1, the identification sends the target transaction message stored in the database fragment to which the fragment number belongs in the remote system to the local system.
Specifically, the data format of the third key-value pair includes:
key = fragment number: value=0 or 1.
The third key value pair "0": for the example of "1", the third key value represents: fragment number 0:1.
s110: and sending the target transaction message to the local system according to the corresponding relation indicated by the third key value pair.
The third key value pair "0": "1", "10": "1" and "20": for example, "0" indicates the correspondence between the third key value pair and the fragment numbers 0 and 1, the fragment numbers 10 and 1, and the fragment numbers 20 and 0. Therefore, the target transaction messages stored in the database fragments to which the fragment number 0 and the fragment number 10 belong are sent to the local system. And for the target transaction message which can be stored in a slicing way by the data of the slicing number 20, the target transaction message is kept to be stored in a different place system.
Obviously, under the condition of the fault of the remote system, the target transaction message in the remote system is determined and sent to the local system according to the corresponding relation indicated by the third key value pair, and the local system performs isolated storage on the target transaction message, so that the loss of the target transaction message stored in the fault database in the remote system in a fragmented manner is avoided.
It should be emphasized that in this embodiment, in the case that the database shards of the remote system or the local system have no fault, the technician may still set the corresponding relationship indicated by the third key value pair according to the operation and maintenance requirement, so as to selectively send the transaction message stored in the database shards under any one of the remote dual-activity systems to the other system.
In summary, according to the corresponding relationship indicated by the first key value pair stored in the preset distributed cache, the transaction message is sent to the local system or the remote system, so as to realize the diversion of the transaction service according to the device number diversion mode. And sending the transaction message to a local system or a remote system according to the corresponding relation indicated by the second key value pair stored in the distributed cache, so that the transaction service is split according to the mode of splitting the organization number. According to the operation and maintenance requirements, setting the corresponding relation indicated by the third key value pair stored in the distributed cache, and sending the transaction message stored in the database under any one system in the different-place double-activity system to the other system, so that the transaction service is split according to the splitting number splitting mode. Therefore, according to the first key value pair, the second key value pair and the third key value pair stored in the distributed cache, the service is split in different required dimensions according to the split mode of the equipment number, the mechanism number and the fragment number, the service splitting effect is obvious, and the applicability is strong.
As shown in fig. 2, a schematic diagram of a method for calculating a fragment number according to an embodiment of the present application includes the following steps:
s201: the number of the sub-tables and the total number of the sub-slices of the database are obtained.
In practical application, whether the local system or the remote system is used, the database is divided into a plurality of database sub-tables, the access data are generated in each database sub-table (namely, the transaction message is stored in the database sub-table), and each database sub-table has a unique number. Specifically, the number of the database sub-tables is 128, namely the database is divided into 128 database sub-tables, and each database sub-table is marked with a unique sub-table number.
In addition, in practical application, the database is segmented into a plurality of database segments, whether the local system or the remote system is adopted, the transaction message is stored in the database segments, and each database segment has a unique segment number.
The specific implementation process of obtaining the number of the sub-tables and the total number of the sub-slices of the database is known as a person skilled in the art, and will not be described herein.
S202: and judging whether the characters indicated by the equipment number of the transaction message are all numbers.
If the characters indicated by the device number of the transaction message are all numbers, S203 is executed, otherwise S204 is executed.
S203: the number indicated by the device number is taken as an integer value.
Specifically, if the device number is 123, the integer value is 123.
S204: and carrying out hash calculation on the character indicated by the equipment number to obtain an integer value.
The specific implementation process of performing hash calculation on the character indicated by the device number to obtain an integer value is known as common general knowledge familiar to those skilled in the art, specifically, the character indicated by the device number is mapped into a unique integer (i.e. hash value) through a hash function, and finally the hash value is used as the integer value.
S205: and calculating the integer value by using the number of the sub-tables of the database to obtain the number of the sub-table of the database to which the database fragment belongs.
S206: and calculating the number by using the total number of fragments of the database to obtain the fragment number of the fragment of the database to which the transaction message belongs.
In summary, the number indicated by the device number is taken as an integer value, or the hash calculation is performed on the character indicated by the device number, so as to obtain the integer value. And calculating the integer value by using the number of the sub-tables of the database to obtain the number of the sub-table of the database to which the database fragment belongs. And calculating the number by using the total number of fragments of the database to obtain the fragment number of the fragment of the database to which the transaction message belongs. Therefore, the embodiment can calculate the fragment number of the database fragment to which the transaction message belongs through the equipment number of the transaction message.
