Vladimir Ozerov updated IGNITE-6201:
------------------------------------
Labels: sql-engine (was: performance)
> SQL: support merge join
> ------------------------
>
> Key: IGNITE-6201
> URL: https://issues.apache.org/jira/browse/IGNITE-6201
> Project: Ignite
> Issue Type: Task
> Components: sql
> Affects Versions: 2.1
> Reporter: Vladimir Ozerov
> Priority: Major
> Labels: sql-engine
>
> It looks like currently the only way to join data is {{nested loops}}
> approach. While being perfectly fine for small tables, this approach is
> terribly inefficient for joins on large tables. We need to make sure that
> merge join technique is used instead if join is performed on sorted
> attributes.
