[jira] [Created] (FLINK-12819) Reuse TableEnvironment between different SQL statements

Zhenghua Gao created FLINK-12819:
------------------------------------

             Summary: Reuse TableEnvironment between different SQL statements
                 Key: FLINK-12819
                 URL: https://issues.apache.org/jira/browse/FLINK-12819
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Client
            Reporter: Zhenghua Gao


We have introduced catalogs to store catalog object(tables, views etc). And the catalogs are tied to TableEnvironment, So we need to reuse TableEnvironment so the previously registered tables and views are available(suppose we use an InMemory catalog).

BTW, reuse TableEnvironment is more resource and time saving.
