representation for map types in descriptor-based Table API
URL: https://github.com/apache/flink/pull/6578#issuecomment-414320931
Thanks for reminding @buptljy. Array types is a bit more complex than map
types. Actually I've already implemented a version on my branch. But it
introduces some implementation tricks, which I thought it would be better to
open another issue to discuss. What is your opinion @twalthr?

> Since 1.6 the recommended way of creating source/sink table is using
> connector/format/schema/ descriptors. However, when declaring map types in
