Vladimir Ozerov updated IGNITE-8384:
------------------------------------
Labels: performance (was: )
> SQL: Secondary indexes should sort entries by links rather than keys
> --------------------------------------------------------------------
>
> Key: IGNITE-8384
> URL: https://issues.apache.org/jira/browse/IGNITE-8384
> Project: Ignite
> Issue Type: Task
> Components: sql
> Affects Versions: 2.4
> Reporter: Vladimir Ozerov
> Priority: Major
> Labels: performance
> Fix For: 2.6
>
>
> Currently we sort entries in secondary indexes as {{(idx_cols, KEY)}}. The
> key itself is not stored in the index in general case. It means that we need
> to perform a lookup to data page to find correct insertion point for index
> entry.
> This could be fixed easily by sorting entries a bit differently - {{idx_cols,
> link}}. This is all we need.
