Vladimir Ozerov updated IGNITE-6626:
------------------------------------
Description:
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
This ticket is to implement row filtering on B+Tree level and avoid their
materialization.
> SQL: Doesn't materialize rows when possible
