Do I need binlogs?

edwhedwh ContributorCurrent User Role Novice
Apologies if this is a FAQ - I've googled some and I can't find a clear answer.

If I am running an XtraDB cluster, with no replication, do I need binlogs?

They're enabled and chewing up disk space. I'm aware I can restrict their number using max_binlog_files, but I'm not sure if I need them at all in a clustered environment. If I don't, I'll turn them off and save some disk space.

    No, binlogs are not required for Galera to work. But you may need them for PITR case.
