[jira] [Created] (IGNITE-7039) SQL: local query should pin affected partitions

Vladimir Ozerov created IGNITE-7039:
---------------------------------------

             Summary: SQL: local query should pin affected partitions
                 Key: IGNITE-7039
                 URL: https://issues.apache.org/jira/browse/IGNITE-7039
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Vladimir Ozerov


When distributed query is executed, we pin cache partitions for particular topology version on map nodes [1]. However, it seems that we do no do that for local queries. This is a bug because partition with required data could be evicted from local node at any time, leading to incorrect results.
