Prevent disabling of binlog #678

vsliouniaev commented 3 months ago

I'm currently using the operator with single DB instances and explicitly disabling binary logging as I don't need replication but a very lightweight implementation.

Is it possible to maintain this behavior?

ymmt2005 commented 3 months ago

I'm afraid not. Even a single cluster needs binlogs for MOCO because we allow users to add replicas later, which needs binlogs.

vsliouniaev commented 3 months ago

What if there was a CRD level option that would allow for this, provided that the number of replicas is 1? That would be easier to validate.

@masa213f @d-kuro thoughts?

@vsliouniaev @ymmt2005 Can _includ be used? https://cybozu-go.github.io/moco/usage.html?highlight=_inc#opaque-configuration

ymmt2005 commented 3 months ago

yup, that should work.
