Hi community, In CALCITE-5918[1], I have added a Map function (Spark Library).
We have supported a lot of array/map functions (Spark) in recent versions of calcite, and it seems that only the most basic MAP function is left. The PR links is: https://github.com/apache/calcite/pull/3459 If someone has time, please help me to review this PR, thanks.
