Why is Logger's default level :debug?

What’s the bar for breaking compatibility? There’s some precedent for doing so when it prevents confusion:

Yeah, I know, that is my work.

I 100% agree with you that default of :debug is wrong and should be changed, ideally to match Erlang’s :notice, as it would make a lot of stuff much easier.

@asweet-confluent

Can Logger reliably distinguish between an explicitly configured log level and falling back to its implicit :debug default?

Unfortunately - no. If that would be possible then I would propose that in the first place, but there is no way to detect that.

I hate logging systems that hide messages by default from me.

When initially developing I want to see all the messages without having to mind about configuration.

I believe that the default configuration of logger should match the production environment, not dev. Dev environment is form of special environment, and accidental leakage of private data (which may be logged in debug logs) is bigger issue IMHO.
