Abstract

The invention relates to a data processing method and device, computer equipment and a storage medium. The method comprises the following steps: receiving a read request, wherein the read request carries a session identifier; acquiring a primary library synchronization log site corresponding to the session identifier; receiving a slave library synchronization log site reported by the slave library; when the synchronization log site of the master library is larger than or equal to the synchronization log site of the slave library, a read request is sent to the master library, and when the synchronization log site of the master library is smaller than the synchronization log site of the slave library, the read request is sent to the slave library. A master library synchronization log site of each session is stored in an agent layer, the offset of a request in a change log in a master library, namely a synchronization log site, and a synchronization log site reported by a slave library are determined according to a session identifier in a read request, and whether the current synchronization log site of the slave library exceeds the synchronization log site of the master library is judged; if yes, the data are read through the slave library, otherwise, the data are read through the master library, and the reading pressure of the master library is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, device, computer equipment and storage medium. Background technique [0002] In the read expansion scenario, industry databases generally adopt a read-write separation architecture. That is, the write request is sent to the master library through the proxy layer, and the read request is sent to the slave library. Since there is a certain synchronization delay between the master and the slave, the read-write consistency of business access cannot be guaranteed, only the final consistency can be guaranteed. In order to solve the above problems, the business is split, and the read and write requests required by strong consistency are directly connected to the main library, and the part of final consistency can be separated from reading and writing. The above method directly connects strongly consistent read and write requests to the main li...
