Wenlong Lyu commented on FLINK-17139:
-------------------------------------
in 1.10 the compile for each dml is eager:
StreamTableEnvironmentImpl#isEagerOperationTranslation return true, so we can't
reuse the source. I believe that it is solved in master.
> The sub-plan reuse optimizer can't reuse sub-plan that from different sql
> node tree
