Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The flow provided by the embodiment of the application is applied to the remote dual-active system and is used for effectively shunting the service to systems in different areas.
In the practical application process of service distribution, 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 has been used for a long time, and the security trust level is higher, so that in consideration of security trust, and in order to ensure the processing efficiency and stability of the service, only a small amount of services are shunted aiming at the initial stage of the deployment of the remote system, that is, the services with small amount are switched from the local system to the remote system to be executed, so as to verify whether the remote system has the capability of undertaking service shunting. In the process of service initiation, a service initiation device (e.g., pos machine) or a service initiation merchant (e.g., a merchant at some place) is usually used as a service initiator. For the service initiating device, the number of service initiations is small, and one service initiating device usually initiates only one service in a limited time. For the service initiating merchant, because the service initiating merchant includes a larger number of service initiating devices, the number of initiated services is larger compared to the case where the service initiating device is used as a service initiating party.
Therefore, for the distribution situation of a small amount of services, it can be realized to distribute a small amount of services to a different-place system by using one service as a distribution dimension in a manner of distributing the service according to the equipment number (i.e. the number of the service initiating equipment, for example, the number of the pos machine: 0123). For example, 100 service initiating devices each initiate two services within one hour. And sending 400 services after carrying out service initiation for 2 hours in total, selecting a small amount of services (for example, 50 services) from the 400 services, distributing the 50 services to a remote system according to a device number distribution mode, and distributing the remaining 120 services to a local system.
After the shunting verification of a small amount of services is performed, it is determined that the remote system has the capability of undertaking service shunting, and then a large amount of services can be shunted to the remote system by using a service set as a shunting dimension in a shunting manner of an organization number (a code of a region to which a service initiating merchant belongs, such as 1020000-Anhui). For example, 10 service-initiating merchants respectively initiate 1000 services within one hour, 10000 services are initiated within 1 hour in total, and the local system and the remote system respectively 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 mechanism number distribution mode.
In addition, whether the local system or the remote system is used, the database fragment for storing the service packet (usually, the service initiator specifically sends the service packet to the local system or the remote system in the process of initiating the service) may be unusable due to individual reasons. In the operation and maintenance process of the remote dual-active system, aiming at the condition that the database fragments in the remote system cannot be used, the service messages stored by the fault database fragments can be switched to the local system for processing according to the fragment number distribution mode. Of course, when the local system fails, the service message stored in the local system may also be sent to the remote system in a split number splitting manner. In addition, under the condition that the database fragments in the local system or the remote system are not in fault, in order to realize the operation and maintenance requirements, the service message stored by the database fragment of any system can be sent to another system in a fragment number distribution mode. For example, a mysql database is adopted by the remote system, a certain database fragment of the mysql database cannot be used, and in the process of operation and maintenance of the remote system, a service message stored under the failed 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 above findings of the applicant, the embodiments of the present application provide the following technical solutions: fig. 1 is a schematic view of a service offloading method provided in an embodiment of the present application, and a transaction service is taken as an example in the method shown in fig. 1 for description.
The process shown in fig. 1 may be executed by a server, specifically, the server receives a transaction packet sent by a service initiator, and determines a sending object of the transaction packet according to configuration information stored in a distributed cache, in this embodiment, fig. 1 includes the following steps:
s101: and acquiring a transaction message.
S102: and unpacking the transaction message to obtain the equipment number and the organization number.
The transaction message includes the device number and the institution number, and the specific implementation process of unpacking the transaction message to obtain the device number and the institution number is common general knowledge familiar to those skilled in the art and will not be described herein again.
S103: and reading a preset distributed cache, and judging whether the configuration information of the equipment number exists in the distributed cache. If the configuration information of the device number exists in the distributed cache, executing S104, otherwise executing S105.
The configuration information of the device number includes a first Key-Value pair (Key-Value) used to indicate a correspondence between the device number and a cluster name, where 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 shanghai south cluster, and the cluster name of the remote system is wuhan south cluster).
It should be noted that, the cluster is a commonly used technology of the existing service system, the cluster is a group of mutually independent computers interconnected through a high-speed network, the computers form a group and are managed in the 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 is the equipment number: value is the name of the cluster.
By the first key value pair "abcdefgh": for "whsouthwgroup" as an example, the first key-value pair represents: device number abcdefgh: wuhan southern 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, each cache node is equal, the problem of cache failure 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.
By the first key value pair "abcdefgh": "whSouthGroup" and "abd": for example, "shSouthGroup" indicates the correspondence between the device number abcdefgh and the southern wuhan cluster, and the device number abd and the southern shanghai cluster, where the southern wuhan cluster belongs to a foreign system and the southern shanghai cluster belongs to a local system, and thus, the transaction message of the device number abcdefgh is sent to the foreign system. And sending the transaction message of the equipment number abd to a local system.
Obviously, the sending object of the transaction message is determined according to the corresponding relation indicated by the first key value pair, so that a small amount of services can be distributed to a remote system by taking one service as a distribution dimension, in other words, the services can be distributed to the remote system according to the equipment number distribution mode.
S105: and judging whether the configuration information of the organization number exists in the distributed cache. If the configuration information of the organization number exists in the distributed cache, S106 is executed, otherwise S107 is executed.
The configuration information of the organization number comprises a second key value pair, and the second key value pair is used for indicating the corresponding relation between the organization number and the cluster name.
Specifically, the data format of the second key-value pair includes:
key is the mechanism number: value is the name of the cluster.
With the second key-value pair "101600": for example, "shSouthGroup," the second key-value pair represents: agency No. 101600: shanghai south 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, "southwgroup" indicates the correspondence between organization number 101 and the south wuhan cluster, which belongs to a foreign system, and organization number 101600 and the south shanghai cluster, which belongs to a local system. The number of transaction messages with organization number 101 is 1000, and the number of transaction messages with organization number 101600 is 1000. Therefore, 1000 transaction messages of the organization number 101 are sent to the remote system. And sending 1000 transaction messages of the organization number 101600 to the local system.
Obviously, the sending object of the transaction message is determined according to the corresponding relation indicated by the second key value pair, so that a large number of services can be distributed to a different-place system by taking the service set as a distribution dimension, in other words, the services can be distributed to the different-place system according to the equipment number distribution mode.
S107: and sending the transaction message to a local system.
Since the distributed cache does not have the configuration information of the device number and the mechanism number, the transaction message can only be sent to the local system, that is, the service distribution is not performed.
S108: and under the condition that the database fragment of the remote system has a fault, acquiring a target transaction message from the remote system, and calculating the fragment number of the database fragment to which the target transaction message belongs through the equipment number obtained by unpacking the target transaction message.
The specific implementation process of calculating the fragment number of the database fragment to which the target transaction message belongs through the device number of the target transaction message may refer to the following steps shown in fig. 2 and an explanation of the steps.
Optionally, when a 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 device number obtained by unpacking the transaction message.
S109: and changing the configuration information of the fragment number prestored in the distributed cache, so that the changed configuration information indicates the corresponding relation between the fragment number and the local system.
The configuration information of the slicing number comprises a third key value pair, the third key value pair is used for indicating the corresponding relation between the slicing number and a preset numerical value, and the preset numerical value indicates 0 or 1.
It should be noted that, when the preset value indicates 0, it indicates that the target transaction message stored in the database segment to which the segment number belongs in the remote system is sent to the local system. And when the preset numerical value indicates 1, the identifier sends a 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 is the number of fragmentation: value is 0 or 1.
"0" by third key value: "1" is an example, and the third key value pair represents: fragment number 0: 1.
s110: and sending the target transaction message to a local system according to the corresponding relation indicated by the third key value pair.
"0" by third key value: "1", "10": "1" and "20": "0" is an example, and the third key value pair indicates the correspondence of the slice numbers 0 and 1, the slice numbers 10 and 1, and the slice numbers 20 and 0. Therefore, the target transaction message stored in the database fragment to which the fragment number 0 and the fragment number 10 belong is sent to the local system. And keeping storing the target transaction message of which the data to which the fragment number 20 belongs can be stored in a remote system in a fragment mode.
Obviously, under the condition of a fault of the remote system, the target transaction message in the remote system is determined according to the indicated corresponding relation of the third key value pair and is sent to the local system, and the local system carries out isolated storage on the target transaction message, so that the target transaction message stored in the fault database in the remote system in a fragmentation mode is prevented from being lost.
It should be emphasized that, in this embodiment, in the case that the database fragment of the remote system or the local system has 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 fragment of any one of the remote dual-active systems to the other system.
In summary, the transaction message is sent to the local system or the remote system according to the corresponding relationship indicated by the first key value pair stored in the preset distributed cache, so that the transaction service is distributed according to the equipment number distribution 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, thereby realizing the shunting of transaction services according to the mechanism number shunting mode. And setting the corresponding relation indicated by the third key value pair stored in the distributed cache according to the operation and maintenance requirements, and sending the transaction message stored in the database in a fragmentation mode under any one system in the remote dual-active system to the other system, thereby realizing the shunting of transaction services according to the fragmentation number shunting mode. As can be seen, in this embodiment, 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 shunted in different demand dimensions according to the shunting manner of the device number, the organization number, and the fragmentation number, and the service shunting effect is significant, and the applicability is strong.

s201: and acquiring the sub-table number and the total fragment number of the database.
In practical application, no matter a local system or a remote system, the databases are divided into tables, the general table is divided into a plurality of database sub-tables, the access data is 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, that is, the database is divided into 128 database sub-tables, and each database sub-table is labeled with a unique sub-table number.
In addition, in practical application, no matter a local system or a remote system, the database is also fragmented, the database is divided into a plurality of database fragments, the transaction message is stored in the database fragments, and each database fragment has a unique fragment number.
The specific implementation process for obtaining the number of the sub-tables and the total number of the sub-tables of the database is common knowledge familiar to those skilled in the art, and will not be described herein again.
S202: and judging whether the characters indicated by the equipment number of the transaction message are all numbers.
If all the characters indicated by the device number of the transaction message are numbers, executing S203, otherwise executing S204.

S205: and (4) carrying out remainder on the whole numerical value by utilizing the number of the sub-tables of the database to obtain the serial number of the sub-tables of the database to which the database fragments belong.
S206: and (4) the total number of the fragments of the database is utilized to carry out remainder on the serial number to obtain the fragment number of the database fragment to which the transaction message belongs.
To sum up, the number indicated by the device number is used as an integer value, or the hash calculation is performed on the character indicated by the device number to obtain an integer value. And (4) carrying out remainder on the whole numerical value by utilizing the number of the sub-tables of the database to obtain the serial number of the sub-tables of the database to which the database fragments belong.
