> Similar to https://issues.apache.org/jira/browse/FLINK-4554
> We want to support Map value constructor which is supported by Calcite:
> https://calcite.apache.org/docs/reference.html#value-constructors
> {code:sql}
> SELECT
> MAP['key1', f0, 'key2', f1] AS stringKeyedMap,
> MAP['key', 'value'] AS literalMap,
> MAP[f0, f1] AS fieldMap
> FROM
> table
> {code}
> This should enable users to construct MapTypeInfo, one of the CompositeType.
