---------------------------------------------
Recently, I bumped into the following article [Implementing Common Table
Expressions for MariaDB|http://ceur-ws.org/Vol-1864/paper_6.pdf]. It might be
another useful resource when we decide to tackle this issue.

> 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.
