> With the new ability to support null values in Druid, empty string is not equal to null anymore.
> To enable auto format parser {code}timestamp_parse{code} Druid function expects null literal as format argument.
> I have added a connection config parameter to allow smooth transition from old Druid version to version 0.13.0 and above.
