@vvysotskyi thanks for the explanations. I am mostly good with the PR..so
its a +1 from me but it would be good if @gparai can take a quick look at the
statistics related changes.

> Key: DRILL-7089
> URL: https://issues.apache.org/jira/browse/DRILL-7089
> Project: Apache Drill
> Issue Type: Sub-task
> Affects Versions: 1.16.0
> Reporter: Volodymyr Vysotskyi
> Assignee: Volodymyr Vysotskyi
> Priority: Major
> Fix For: 1.16.0
>
>
> In the scope of DRILL-6852 were introduced new classes for metadata usage.
> These classes may be reused in other GroupScan instances to preserve heap
> usage for the case when metadata is large.
> The idea is to store {{BaseMetadata}} inheritors in {{DrillTable}} and pass
> them to the {{GroupScan}}, so in the scope of the single query, it will be
> possible to reuse them.
