Yury Gerzhedovich commented on IGNITE-17813:
--------------------------------------------
[~slukyanov], Calcite is pretty smart and your suggested WA will not work due
to Calcite will rewrite the query. So, the ticket is still actually for
3.0.0-beta1
> Sql. Introduce sorted reducer for IndexScanNode

> This task is derived from IGNITE-17655 to reduce its scope.
> Currently, IgniteScanNode reads partition after partition which, obviously,
> breaks the sorting order. We need to introduce wrapping cursor, which accepts
> open cursors for every partition, and produce the sorted output.
