-------------------------------------
Hi [~twalthr], Thank you for improving the interface definition！:)
I think `flink-tabe-api-base` also need add `BaseBatchTableEnvironment` and
`BaseStreamTableEnvironment` for Java and scala shared methods, such as
`registerTableSink` etc. So in this way we have added several base classes, but
solved the compatibility problem.
At present, we still have a problem with stream and batch unification, which
means that users do not need to know whether it is batchEnv or StreamEnv. This
change will lead to compatibility issues, which can be discussed and resolved
in another JIRA.
What do you think？
