Fabian Hueske commented on FLINK-2099:
--------------------------------------

The current master branch supports a subset of SQL already and the features 
linked to this issue feel a bit arbitrary. 
Even if all these issues are fixed, we won't support the full set and cannot 
claim "SQL support is done".

Therefore, I propose to close this issue.
We will of course continue to extend the support for SQL features, but I don't 
think we need this issue to track progress.

What do you think [~twalthr]?

> From the mailing list:
> Fabian: Flink's Table API is pretty close to what SQL provides. IMO, the best
> approach would be to leverage that and build a SQL parser (maybe together
> with a logical optimizer) on top of the Table API. Parser (and optimizer)
> could be built using Apache Calcite which is providing exactly this.
> Since the Table API is still a fairly new component and not very feature
> rich, it might make sense to extend and strengthen it before putting
> something major on top.
> Ted: It would also be relatively simple (I think) to retarget drill to Flink 
> if
> Flink doesn't provide enough typing meta-data to do traditional SQL.
