> Key: IGNITE-13179
> URL: https://issues.apache.org/jira/browse/IGNITE-13179
> Project: Ignite
> Issue Type: Improvement
> Reporter: Taras Ledkov
> Assignee: Aleksey Plekhanov
> Priority: Major
> Labels: calcite2-required, calcite3-required
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
