Group Replication Overwrites Auto Increment Variables, but MySQL Shell (GR Used as InnoDB Cluster) Overwrites Them Again in Single-Primary Mode (Doc ID 2445570.1)

Last updated on APRIL 20, 2021

Applies to:

MySQL Server - Version 5.7 and later
Information in this document applies to any platform.


As described <Document 2378550.1>,  group replication overwrites auto_increment_increment and auto_increment_offset system variables when the replication is started. This aims to avoid conflicts for automatically generated ID among group members in multi-primary mode. You might expect that these auto increment related system variables are changed when you are using group replication as InnoDB Cluster with MySQL Shell, however, that is not the case.
