Bowen Li commented on FLINK-10686:
----------------------------------

I'd vote for this, and hope it can be done ASAP so all the coming Flink-Hive integration work
can depend on Java only.

> Because more and more table factories for connectors and formats are added and external
catalog support is also on the horizon, {{flink-table}} becomes a dependency for many Flink
modules. Since {{flink-table}} is implemented in Scala it requires other modules to be suffixes
with Scala prefixes. However, as we have learned in the past, Scala code is hard to maintain
which is why our long-term goal is to avoid Scala/Scala dependencies.
> Therefore we propose a new module {{flink-table-common}} that contains interfaces between
{{flink-table}} and other modules. This module is implemented in Java and should contain minimal
(or better no) external dependencies.
