---------------------------------------
Assignee: Maksim Timonin
> Validate that tables beind joined have the same partition distribution
> ----------------------------------------------------------------------
>
> Key: IGNITE-13975
> URL: https://issues.apache.org/jira/browse/IGNITE-13975
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Stanislav Lukyanov
> Assignee: Maksim Timonin
> Priority: Major
>
> To be able to join two PARTITIONED tables one needs to perform the JOIN on an
> affinity key, and also to make sure that the tables have the same partition
> distribution - otherwise, the result will be incorrect.
> Validation of whether the affinity key is being used for JOIN is to be done
> in https://issues.apache.org/jira/browse/IGNITE-13019.
> The goal of this ticket is to add validation of the partition distribution.
> Whenever a JOIN of PARTITIONED tables is being done, the SQL engine needs to
> ensure that
> * The tables use the same affinity function
> * The tables have the same number of partitions
> * The tables have the same node filters
> Same is for when REPLICATED tables are used and
> `treatReplicatedAsPartitioned=true` (see
> https://issues.apache.org/jira/browse/IGNITE-8732).
