As known from the background art, a hot account is a single account with high concurrent database operations, and if the operation of responding to the hot account is performed in a serial queuing manner, a performance bottleneck is caused. Because the operation speed of the memory is far faster than that of the traditional database, the operation of the memory database responding to the hot spot account is usually adopted at present, and the hot spot account service is responded in the memory, such as cache balance for overdraft control. In an actual application process, when master-slave switching occurs, the situation that data of a master library is not synchronized to a standby library exists, the data of the master library is used for providing hot spot account service by the database with unsynchronized data, abnormal service conditions such as balance control failure or overdraft and the like can be caused, a large risk exists, and adverse effects are easily brought to customers and institutions.
Therefore, the embodiment of the invention provides a hot spot account service method, when a master memory database and a slave memory database are switched, the traditional disk database provides service, and after data synchronization is determined, the memory database is started again to provide service, so that abnormal conditions caused by data asynchronization are avoided.
The embodiment of the invention provides a hot spot account service method, which can be applied to various business systems, wherein an execution main body can be a server of the system, and a method flow chart of the method is shown in figure 1 and comprises the following steps:
s101: when determining that a first memory database in a master-slave database set is abnormal, switching the first memory database from a current master state to a standby state, and switching a second memory database in the master-slave database set from the current standby state to the master state;
in the method provided by the embodiment of the invention, a master-slave database set comprising a first memory database and a second memory database is preset, the first memory database is used as a master database, namely the database in the master state at present, and the second memory database is used as a slave database, namely the database in the standby state at present. In normal conditions, in the process of providing hot account service by a business system, a master database in a master-slave database set responds to database operation of hot accounts, such as account balance modification and the like,
when the current master database (namely the first memory database) in the master-slave database set is abnormal, master-slave switching can be triggered, and the current slave database (namely the second memory database) is upgraded into a new master database.
The memory database in the method provided by the embodiment of the invention can adopt a Redis memory database, and can also adopt other types of memory databases, so that the realization function of the method provided by the embodiment of the invention is not influenced.
S102: switching the master-slave database set from the current account service state to a non-account service state so that the business system stops providing hot account service based on the master-slave database set;
in the method provided by the embodiment of the invention, when the master database and the slave database are switched in the master database and the slave database, the master database and the slave database are switched from the current account service state to the non-account service state, namely, the master database in the master database and the slave database is not adopted to respond to the database operation of the hot account.
S103: switching a disk database of the business system from a current non-account service state to an account service state so that the business system provides hot spot account service based on the disk database;
in the method provided by the embodiment of the invention, a traditional database, namely a disk database, is preset, when a main database in a main database and a slave database set responds to database operation of a hotspot account, an operation result can be asynchronously registered in the disk database, for example, the balance of an account is cached in the main database to perform overdraft control, and the balance registration of a corresponding account is asynchronously performed in the disk database, namely, account data in the disk database is synchronous with account data in the main database.
When the master database and the slave database are switched in the master database and the slave database, the disk database is switched to an account service state, namely the disk database is adopted to respond to database operation of a hot account, such as account balance control.
S104: determining whether the second memory database is synchronized with the latest account data;
in the method provided by the embodiment of the invention, after the master database and the slave database are switched, whether the account data stored in the second memory database which needs to be upgraded into the master database is the latest account data or not can be determined.

And at the moment, the master database in the master-slave database set is the second memory database. And the disk database does not respond to the database operation of the hot spot account any more, and still records the current account data in the master database in the master-slave database set.
Based on the method provided by the embodiment of the invention, if the first memory database in the main state is abnormal, the second memory database in the standby state is switched to the main state, the service system suspends the use of the memory database to provide the hot spot account service, and the disk database is used to provide the hot spot account service. And when the second memory database is determined to be synchronized with the latest account data, the service system resumes using the memory database to provide the hot spot account service. By applying the method provided by the embodiment of the invention, the performance bottleneck caused by high concurrent operation of the hot account can be solved based on the quick reading and writing of the memory database. And a redundant memory database is adopted to provide a hot spot account service, so that the high availability of a service system can be guaranteed.

The running state of the main-use memory database can be detected in real time through the sentinel node to determine whether the abnormality exists. And if the sentinel node detects that the running state of the first memory database is abnormal, determining that the first memory database is abnormal.
In the method provided by the embodiment of the invention, when the sentinel node detects that the memory database in the main state is abnormal, the switching of the master database and the slave database can be triggered, and whether the master database and the slave database are switched is monitored.
On the basis of the method shown in fig. 1, in the method provided by the embodiment of the present invention, the process of switching the master-slave database set from the current account service state to the non-account service state in step S102 includes:
determining a hotspot account service mark corresponding to the master-slave database set;

In the method provided by the embodiment of the invention, a database system corresponding to the master-slave database set is provided with a hot spot account service mark for representing whether a master memory database in the master-slave database set, namely a memory database in a master state, is used, so as to provide hot spot account service.
And configuring a hotspot account service mark corresponding to the master-slave database set as a preset forbidden service parameter through a parameter modification instruction, wherein the preset forbidden service parameter represents that the hot-spot account service is provided without using a master memory database in the master-slave database set.
On the basis of the method provided by the foregoing embodiment, in the method provided by the embodiment of the present invention, the process of switching the master-slave database set from the current non-account service state to the account service state, which is mentioned in step S105, includes:
setting a mark parameter corresponding to the hotspot account service mark as a preset service enabling parameter so as to switch the master-slave database set from a current non-account service state to an account service state.
In the method provided by the embodiment of the invention, the hotspot account service mark can be configured as a preset service enabling parameter through a parameter modification instruction, and the preset service enabling parameter represents that the hotspot account service is provided by using a main memory database in a main database set and a slave database set.
On the basis of the method shown in fig. 1, in the method provided in the embodiment of the present invention, the step of determining whether the second in-memory database has synchronized the latest account data in step S104 includes:
determining first account data corresponding to the disk database;
determining second account data corresponding to the second memory database;
judging whether the first account data is the same as the second account data;
and if the first account data is the same as the second account data, determining that the second memory database is synchronized with the latest account data.
In the method provided by the embodiment of the invention, the account data stored in the disk database, such as each account number and the balance of the account, can be read. And reading account data stored in the second memory database, comparing the account data stored in the disk database with the account data stored in the second memory database, and if the account data stored in the two databases are the same, determining that the second memory database is synchronized with the latest account data.
In the method provided by the embodiment of the invention, after the master-slave database set is switched between the master and the slave, the data stored in the second memory database can be updated into the latest data stored in the disk database, and then the confirmation process is carried out.
In order to better describe the method provided by the embodiment of the present invention, the embodiment of the present invention provides another hot spot account service method, a flowchart of the method is shown in fig. 2, and on the basis of the method shown in fig. 1, the method provided by the embodiment of the present invention further includes:
s106: and if the second memory database does not synchronize the latest account data, acquiring the synchronous account data from the disk database, and storing the synchronous account data to the second memory database.
In the method provided by the embodiment of the present invention, if the second memory database does not synchronously update the latest account data, the synchronous account data, that is, the real-time latest account data, is obtained from the disk database, and the obtained synchronous account data is stored in the second memory database, so that the second memory database synchronizes the latest account data. After the synchronous account data is stored in the second memory database, whether the synchronous account data is synchronized with the latest account data can be confirmed again, so that the subsequent process can be carried out.
In order to better explain the method provided by the embodiment of the invention, the embodiment of the invention provides another hot spot account service method, and the hot spot account service process provided by the embodiment of the invention is further and integrally explained by combining a specific application scene.
In the method provided by the embodiment of the invention, the memory database is a Redis memory database, a sentinel model is adopted to ensure that the Redis memory database is highly available, and a 'whether to start a hot account flag' is set in the Redis memory database: HOT _ ACC _ FLAG, and the value dictionary is YES and NO.
Under normal conditions, data are read and written from the Redis master library, and because the Redis is a memory database, the reading and writing speed is obviously higher than that of the traditional disk database.
When the Redis master library has problems, the sentinel nodes can be automatically switched to the slave libraries, and the slave libraries are upgraded to provide services for the master library.
Due to the fact that data are not synchronized theoretically in the switching process, incomplete data of a new main database exist, and risks such as fund overdraft exist. At the moment, according to the event subscription service provided by the sentinel node, master-slave switching of the Redis memory database is monitored by independently establishing the service. If master-slave switching is monitored, HOT _ ACC _ FLAG is set to be NO, at the moment, the service is degraded to be balance which is not suitable for controlling the Redis memory database, and is reduced to be balance which is controlled by using a disk database, and at the moment, the performance is obviously reduced.
And after the Redis memory database suspends the account service, acquiring the latest accurate balance from the disk database, storing the latest accurate balance into a Redis new main library (new main library), changing HOT _ ACC _ FLAG into YES, and recovering the Redis memory database to provide the high-performance hotspot account service.
In the method provided by the embodiment of the invention, through the sensing of the switching of the master library and the slave library, when the slave library is switched, the transaction is temporarily blocked, and the external service is performed again after the disk database is synchronized to the latest account balance, so that the service continuity can be ensured to the maximum extent, and the account fund security is ensured.

detecting whether the running state of the first memory database is abnormal or not through a preset sentinel node;
and if the sentinel node detects that the running state of the first memory database is abnormal, determining that the first memory database is abnormal.
3. The method of claim 1, wherein switching the master-slave database set from a current account service state to a non-account service state comprises:
determining a hotspot account service mark corresponding to the master-slave database set;
setting a mark parameter corresponding to the hotspot account service mark as a preset service forbidding parameter so as to switch the master-slave database set from the current account service state to a non-account service state.
4. The method of claim 3, wherein switching the master-slave database set from a current non-account service state to an account service state comprises:
setting a mark parameter corresponding to the hotspot account service mark as a preset service enabling parameter so as to switch the master-slave database set from a current non-account service state to an account service state.
5. The method of claim 1, wherein determining whether the second in-memory database has synchronized up-to-date account data comprises:
determining first account data corresponding to the disk database;
determining second account data corresponding to the second memory database;
judging whether the first account data is the same as the second account data;
and if the first account data is the same as the second account data, determining that the second memory database is synchronized with the latest account data.
6. The method of claim 1, further comprising:
and if the second memory database does not synchronize the latest account data, acquiring the synchronous account data from the disk database, and storing the synchronous account data to the second memory database.
7. A hotspot account service device, comprising:
the first switching unit is used for switching the first memory database from the current main state to the standby state and switching the second memory database in the master-slave database set from the current standby state to the main state when the first memory database in the master-slave database set is determined to be abnormal;
the second switching unit is used for switching the master-slave database set from the current account service state to the non-account service state so as to enable the business system to stop providing the hot account service based on the master-slave database set;
the third switching unit is used for switching the disk database of the business system from the current non-account service state to the account service state so that the business system provides hot spot account service based on the disk database;
the determining unit is used for determining whether the second memory database is synchronized with the latest account data;
and the fourth switching unit is used for switching the master-slave database set from the current non-account service state to the account service state and switching the disk database from the current account service state to the non-account service state if the second memory database synchronizes the latest account data, so that the service system provides hot spot account service based on the second memory database.
8. The apparatus of claim 7, further comprising:
and the synchronization unit is used for acquiring the synchronous account data from the disk database and storing the synchronous account data into the second memory database if the second memory database does not synchronize the latest account data.
9. A storage medium, comprising stored instructions, wherein when executed, the instructions control a device on which the storage medium is located to execute the hotspot account service method according to any one of claims 1 to 6.
10. An electronic device comprising a memory and one or more instructions, wherein the one or more instructions are stored in the memory and configured to be executed by the one or more processors to perform the hotspot account service method of any one of claims 1-6.
