[jira] [Created] (IGNITE-13179) Calcite integration. Fix traits at the IgniteLimit

Taras Ledkov created IGNITE-13179:
-------------------------------------

             Summary: Calcite integration. Fix traits at the IgniteLimit
                 Key: IGNITE-13179
                 URL: https://issues.apache.org/jira/browse/IGNITE-13179
             Project: Ignite
          Issue Type: Improvement
            Reporter: Taras Ledkov
            Assignee: Taras Ledkov


Current implementation of {{IgniteLimit}} doesn't  support distribution trait propagation.
Limit must require singleton distribution.

Now we cannot reproduce invalid behavior (see IGNITE-12819) and IgniteLimit isn't placed under the Exchange node.

Also Limit must be propogated (copied) under Exchange to reduce unnecessary fetches.
