[jira] [Created] (IGNITE-17813) Sql. Introduce sorted reducer for IndexScanNode

Konstantin Orlov created IGNITE-17813:
-----------------------------------------

             Summary: Sql. Introduce sorted reducer for IndexScanNode
                 Key: IGNITE-17813
                 URL: https://issues.apache.org/jira/browse/IGNITE-17813
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Konstantin Orlov


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.
