Hi Mans,
no, non-equi joins are not supported by the relational APIs because they can be
prohibitively expensive to compute.There's one exception. Cross joins where one
of the input tables is guaranteed to have a single row (because it is the
result of a non-grouped aggregation) are supported in the batch Table API / SQL.
The documentation shows which types of joins are supported including examples
(Table API [1], SQL [2]).
With the upcoming 1.4 release, windowed joins will be added for streaming
queries.
Best, Fabian

Hi:
Is it possible to perform non-equi joins in Flink using the core or relational
apis ? Is there any documentation on what sort of joins are supported with
their examples ?
Thanks
Mans
