> FLINK-6377 introduced the map type for the Table & SQL API. We still need to
> implement functions around this type:
> - the value constructor in SQL that constructs a map {{MAP ‘[’ key, value [,
> key, value ]* ‘]’}}
> - the value constructur in Table API {{map(key, value,...)}} (syntax up for
> discussion)
> - {{ELEMENT, CARDINALITY}} for SQL API
> - {{.at(), .cardinality(), and .element()}} for Table API in Scala & Java
