Distributed table lock application methods, apparatuses, storage media, and electronic devices

Abstract

This specification discloses example distributed table lock application methods and apparatuses, storage media, and electronic devices. In an example method, a master node receives a data processing request and determines a data table that to-be-processed data corresponding to the data processing request are located in. The master node generates a table lock for the data table; performs a lock operation on the data table and generates lock status information corresponding to the data table; writes the lock status information into a local log of the master node and synchronizes the log to a slave node such that the slave node stores the log. After the master node restarts, determines whether the master node stores the log; and in response to that the master node stores the log, restores the lock operation on the data table based on the lock status information recorded in the log.
