-------------------------------
Summary: Support higher precision of TIMESTAMP type as rowtime
attribute
Key: FLINK-15528
URL: https://issues.apache.org/jira/browse/FLINK-15528
Project: Flink
Issue Type: New Feature
Components: Table SQL / Planner
Reporter: Jark Wu
Currently, we only support TIMESTAMP(3) as rowtime attribute. But Blink planner
already opened the door for TIMESTAMP(9). And many built-in functions will
return TIMESTAMP(9), e.g. {{TO_TIMESTAMP(VARCHAR)}}, see FLINK-14925.
If a user use TO_TIMESTAMP(log) to parser a string to timestamp and want use it
as rowtime attribute, it will fail because the 9 precision. I would be more
convenient for users if we can support TIMESTAMP(9) as rowtime attribute.
