Stamatis Zampetakis commented on CALCITE-6352:
----------------------------------------------
It seems that more discussion is needed to converge on a solution and there
hasn't be much progress in the last 6 months so I will remove the fix version
for now. If someone is planning to push this forward please set the fix version
to 1.40.0.
> The map_contains_key function may return true when the key and mapkeytype
> types are different.
