Jark Wu commented on FLINK-20970:
---------------------------------
Hi [~ana4], could you share the full example including the source DDL? This
mostly because of the wrong type defined in the source.
Besides, did you try this on the 1.12.0? This might not happen in the new
version.
> DECIMAL(10, 0) can not be GROUP BY key.
