Review comment:
Looks like `maxRowCount` is taken from avatica. Does it provide similar
functionality we want to implement?

> Key: DRILL-7048
> URL: https://issues.apache.org/jira/browse/DRILL-7048
> Project: Apache Drill
> Issue Type: New Feature
> Components: Client - JDBC, Query Planning & Optimization
> Affects Versions: 1.15.0
> Reporter: Kunal Khatua
> Assignee: Kunal Khatua
> Priority: Major
> Labels: doc-impacting
> Fix For: 1.17.0
>
>
> With DRILL-6960, the webUI will get an auto-limit on the number of results
> fetched.
> Since more of the plumbing is already there, it makes sense to provide the
> same for the JDBC client.
> In addition, it would be nice if the Server can have a pre-defined value as
> well (default 0; i.e. no limit) so that an _admin_ would be able to ensure a
> max limit on the resultset size as well.
