There is difference between retention.bytes and retention.ms. Yes, retention.bytes can be set to -1, but nowhere in the docs says about retention.ms = -1
It might be possible that using -1 it's accepting as a "Value" - which means it might not be validating. But it's not on official docs. I would not be using this if official docs isn't supporting the same. Could anyone else shed some light on this?
