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

             Summary: SQL: Drop _VER field support
                 Key: IGNITE-10986
                 URL: https://issues.apache.org/jira/browse/IGNITE-10986
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov
            Assignee: Alexander Lapin
             Fix For: 2.8


{{_VER}} is undocumented hidden field which is never used in practice. But profiling shows
that it consumes a lot of memory. Let's drop support of this field from all {{GridH2SearchRow}}
implementations, as well as from internal descriptors.
