[jira] [Created] (FLINK-17892) Dynamic option may not be a part of the table digest

hailong wang created FLINK-17892:
------------------------------------

             Summary: Dynamic option may not be a part of the table digest
                 Key: FLINK-17892
                 URL: https://issues.apache.org/jira/browse/FLINK-17892
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Planner
    Affects Versions: 1.11.0
            Reporter: hailong wang
             Fix For: 1.12.0


For now, Table properties not be a part of table digest, but dynamic option will be included.

This will lead to an error when plan reused.

if I defines a kafka table:
{code:java}
CREATE TABLE KAFKA (
……
) with (
topic = 'xx',
groupid = 'xxx'
……
)
Insert into sinktable select * from KAFKA;
Insert into sinktable1 select * from KAFKA;{code}
KAFKA source will be reused according to the SQL above.

But if i add different table hint to dml, like:
{code:java}
Insert into sinktable select * from KAFKA /*+ OPTIONS('k1' = 'v1')*/;
Insert into sinktable1 select * from KAFKA /*+ OPTIONS('k2' = 'v2')*/;
{code}
There will be two kafka tableSources  use the same groupid to  consumer the same topic.

So I think dynamic option may not be a part of the table digest.
