> Document Apache Ignite 2 Calcite SQL recursive CTE support added by
> IGNITE-27822 / PR https://github.com/apache/ignite/pull/13479.
> The docs should cover:
> * WITH RECURSIVE support in the Calcite-based SQL engine;
> * supported UNION ALL recursive CTE shape, including hierarchy traversal /
> sequence-style examples;
> * the current limitation that UNION DISTINCT is not supported yet;
> * recursive CTE execution is coordinator-side for the recursive delta and is
> accounted by Calcite query memory quotas;
> * the distributed property sql.calcite.recursiveCteIterationLimit, default
> 100, and that a negative value disables the limit.
> Suggested pages:
> * docs/_docs/SQL/sql-calcite.adoc for usage, limits, and property details;
> * docs/_docs/sql-reference/sql-conformance.adoc to remove or narrow the stale
> statement that recursive WITH fails in Ignite.
