[jira] [Created] (IGNITE-13677) Calcite integration. TableSpool

Taras Ledkov created IGNITE-13677:
-------------------------------------

             Summary: Calcite integration. TableSpool
                 Key: IGNITE-13677
                 URL: https://issues.apache.org/jira/browse/IGNITE-13677
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Taras Ledkov
            Assignee: Taras Ledkov


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.
