---------------------------------------

             Summary: SQL: IndexingQueryCacheFilter should use immediate partition data if
possible
                 Key: IGNITE-6624
                 URL: https://issues.apache.org/jira/browse/IGNITE-6624
             Project: Ignite
          Issue Type: Task
          Components: cache, sql
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
             Fix For: 2.4


We need to filter backup keys during query execution. Currently to achieve this we do the
following:
1) Get row link
2) Materialize the row (!!!)
3) Create H2 row (H2 wrapping)
4) Then get key from H2 row (unwrapping)
5) Calculate partition through affinity function

What it might look like:
1) Get row link
2) Get partition from link

p.1 is very simple to implement. p.2 might be harded and probably should be implemented out
of scope of this ticket.
