Data processing method and device

Abstract

The invention discloses a data processing method and device. The method includes: receiving a data acquisition request carrying a data identifier, searching whether first data corresponding to the data identifier exists in a distributed cache server or not, if not, judging whether the data identifier is locked or not, if yes, judging whether second data corresponding to the data identifier is cached in a local cache of an application server or not, and if yes, responding to the data acquisition request based on the second data. Through the method and the device, the situation that the data corresponding to the data identifier stored in the distributed cache server is different from the data corresponding to the data identifier stored in the database can be avoided; backlog on a large number of data acquisition request application servers can be avoided, and since no large number of data acquisition request application servers are backlog, the application servers can continue to normally receive other data processing requests subsequently, and the possibility of downtime of the application servers and a database can be reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] With the rapid development of technology, there are more and more application servers on the network, and the application servers can provide data services for users. [0003] Users can access the application server to obtain data, the application server communicates with the database, and the database is used to store data. When the user needs to obtain data, the application server can obtain data from the database and respond to the user. Furthermore, the application server can use the distributed cache server to cache the data in the database, so that the application server can obtain data from the distributed cache server and respond to the user, and the application server can obtain data from the distributed cache server faster than the application server. The speed at which the server obtains da...

Problems solved by technology

[0006] However, during the waiting period, if the application server receives a large number of data acquisition requests for obtaining the above data, since the process of updating the data in the database has not been completed during this period, all data acquisition requests corresponding to "The operation of obtaining data from the database" needs to be suspended. In this way, a large number of data processing requests will be backlogged on the application server, which may cause the application server to fail to receive other data processing requests normally.

[0007] And, if the backlog of data processing requests on the application server is very large, it will increase the possibility of application server and database downtime

[0008] Moreover, if the backlog of data processing requests on the application server is very large, after the process of updating data in the database is completed, although the application server can continue to perform the "operation of obtaining data from the database", it often cannot complete the operation in a short period of time. Respond to all data processing requests for obtaining the above data, which will cause a large number of data processing request responses to time out
