[jira] [Created] (IGNITE-18689) Sql. Introduce heuristics to put spools into the plan

Konstantin Orlov created IGNITE-18689:
-----------------------------------------

             Summary: Sql. Introduce heuristics to put spools into the plan
                 Key: IGNITE-18689
                 URL: https://issues.apache.org/jira/browse/IGNITE-18689
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Konstantin Orlov


Rewindability trait was eliminated in IGNITE-18213, and the spool node is no more participate in query optimisation process. Let's do some research on if there are such queries which may leverage the table/index spools in order to speed up the execution, and if they are, let's introduce (perhaps) heuristic rule to put spool node for such queries.
