>                 Key: IGNITE-29203

>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Vladislav Pyatkov
>            Assignee: Vladislav Pyatkov

> h3. Motivation
> Keys containing ROW values may be compared and hashed by reference, while sorting ROW and ARRAY values fails with ClassCastException. Use content-based equality and hashing for execution keys and SQL distribution, and recursive comparison for sorting.
> h3. Definition of Done
> * DISTINCT produces correct results with colocated and map/reduce hash and sort aggregation.
> * Tests cover equal keys on different nodes, nested values, and NULL handling.
