          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Kaibo Zhou

Currently TableEnvironment only supports register ScalarFunction, it is necessary to support register TableFunction which is written in Java.

The motivation is to eliminate most differences between batch and stream execution environment, and use TableEnvironment only to write programs.
