------------------------------------
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.
