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.
