> SQL: Doesn't materialize rows when possible
> -------------------------------------------
>
> Key: IGNITE-6626
> URL: https://issues.apache.org/jira/browse/IGNITE-6626
> Project: Ignite
> Issue Type: Task
> Components: cache, sql
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Labels: performance
> 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
> This ticket is to implement row filtering on B+Tree level and avoid their
> materialization.
