[jira] [Created] (CALCITE-7095) Allow MAP to be indexed by any type of key

Mihai Budiu created CALCITE-7095:
------------------------------------

             Summary: Allow MAP<VARIANT, X> to be indexed by any type of key
                 Key: CALCITE-7095
                 URL: https://issues.apache.org/jira/browse/CALCITE-7095
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.40.0
            Reporter: Mihai Budiu


Today a MAP with VARIANT keys will not typecheck if it is indexed by a key with a non-variant type. I think the compiler should accept any type of key for this case.

E.g., the following SQL should be legal:

{code:sql}
SELECT CAST(MAP['a', 1] AS MAP<VARIANT, VARIANT>)['a'] AS C
{code}
