------------------------------------------------
Summary: Reduce the planning time of queries on large Parquet
tables with large metadata cache files
Key: DRILL-7028
URL: https://issues.apache.org/jira/browse/DRILL-7028
Project: Apache Drill
Issue Type: Improvement
Components: Metadata
Reporter: Venkata Jyothsna Donapati
Assignee: Venkata Jyothsna Donapati
Fix For: 1.16.0
If the Parquet table has a large number of small files, the metadata cache
files grow larger and the planner tries to read the large metadata cache file
which leads to the planning time overhead. Most of the time of execution is
spent during the planning phase.
