---------------------------------------------------------------
[~ovidiumarcu] It would be very nice to have someone else helping me with that
task. If the main issues of the Table API are solved, I think I can move the
SQL code to flink-contrib or flink-staging. So that more people can work on it
and open PR against it.
[~fhueske] You are right. Supporting TPC-H queries first was also my initial
thought because of less and simpler queries. However, we still have the license
problem with generated data (see FLINK-705). Meanwhile, I think we should use
TPC-DS because there is already an Apache-licensed generator/validator tool:
https://github.com/julianhyde/tpcds
It is in Maven central it can thus easily integrated for ITCases.

> Add a SQL API
> -------------
>
> Key: FLINK-2099
> URL: https://issues.apache.org/jira/browse/FLINK-2099
> Project: Flink
> Issue Type: New Feature
> Components: Table API
> Reporter: Timo Walther
> Assignee: Timo Walther
>
> 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.
