> Key: IMPALA-12549
> URL: https://issues.apache.org/jira/browse/IMPALA-12549
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: performance

> With small strings, the queries consume less memory.
> We should adjust the memory estimations / min reservations to take the small
> strings into account.
> At first we can be conservative, i.e. only take them into account for columns
> with max size less than the small string limit.
