> The first step of the IGNITE-13545: adds TableSpool.
> We have to add new trait: {{CorretlationTrait}} to check stream correlation.
> Without check this trait Filter with correlated variables may be places under Exchange.
> So, {{IgniteCorrelatedNestedLoopJoin}} requires correlated stream from the right input and {{Exchange}} may produce only uncorrelated stream.
