The --log-bin option is used for replication and point-in-time recovery. With MySQL 8.0, the default setting for the --log-bin option has changed from OFF to ON.
Consult your database administrator for assistance with the recommended -log-bin setting for your organization.
- If you use replication or point-in-time recovery —Make sure that the new default setting is appropriate for your environment.
- If you do not use replication or point-in-time recovery —It is recommended that you change the
--log-binoption toOFFto prevent extra disk space from being used.
