Problems solved by technology

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a method for reading from a library, a device for reading from a library, a device for reading from a library, and a computer-readable storage medium to solve problems caused by global locks. If the force is too large, the delay of the request will increase significantly, the QPS will drop, and there will be many technical problems of slow logs on the slave library

Abstract

The invention discloses a slave library reading method. The method comprises: starting a master library and a slave library to perform data synchronization; receiving a reading request for the slave library when the slave library is allowed to be read when the master library and the slave library are subjected to data synchronization; and for the reading request, reading the slave library according to the recorded state of the transaction in an underlying storage engine, and outputting a reading result. The invention further discloses a slave library reading device and equipment, and the technical problems that due to the fact that the overall lock strength is too large, the request delay is obviously increased, QPS is lowered, and many slow logs appear on the slave library are solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for reading from a library, a related device and equipment. Background technique [0002] Database (Database) is a warehouse that organizes, stores and manages data according to the data structure; with the development of information technology and the market, especially after the 1990s, data management is no longer just storing and managing data, but changing Various data management methods required by users. There are many types of databases, ranging from the simplest tables storing various data to large database systems capable of storing massive amounts of data, which have been widely used in various aspects. [0003] Due to the consideration of data disaster recovery, load balancing, data centralization and distribution, etc., databases in the prior art generally establish master-slave databases, that is, master databases and slave databases. At present, in the process of...
