Fabian Hueske commented on FLINK-7798:
--------------------------------------
Yes, it's a bit of effort to get all the pieces that we would need for the
conversion.
Moreover, I identified another problem. At this level, join predicates might
also be present in a Filter that succeeds the Join operator.
Let's just remove the check for the StreamExecutionEnvironment, add plan
validation tests, and adapt the documentation.
> Add support for windowed joins to Table API

> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Fabian Hueske

> Priority: Critical
> Fix For: 1.4.0

>
> Currently, windowed joins on streaming tables are only supported through SQL.
> The Table API should support these joins as well. For that, we have to adjust
> the Table API validation and translate the API into the respective logical
> plan. Since most of the code should already be there for the batch Table API
> joins, this should be fairly straightforward.
