------------------------------------------
Summary: Implement caching of BaseMetadata classes
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
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.
