> There are logging guards here checking for TRACE level debugging but the
> logging is actually INFO. This is important logging for detecting data skew.
> Please change guards to check for INFO... or I would prefer that the guards
> are removed altogether since it's very rare that a service is running with
> only WARN level logging.
