---------------------------------------------
Hi [~wa.moustafa], I see you were involved in the discussion about adding
recursion to Calcite. Is there any work in progress related with this subject
available somewhere? We may start working on this Jira in the near future, so
it would be nice to know if there is already some code somewhere, which we can
re-use.

> Project: Calcite
> Issue Type: Improvement
> Reporter: GitHub Import
> Priority: Major
> Labels: github-import
>
> Building on https://github.com/julianhyde/optiq/issues/128, enable the
> RECURSIVE keyword.
> This feature allows relations to be computed iteratively. Whereas
> ([#128|https://github.com/JulianHyde/optiq/issues/128] |
> [FLINK-128|https://issues.apache.org/jira/browse/OPTIQ-128]) was mainly a
> parser/validator change, this feature requires significant changes to the
> planner and runtime.
