------------------------------------
Summary: Add additional logging and metrics to the Parquet reader
Key: DRILL-4152
URL: https://issues.apache.org/jira/browse/DRILL-4152
Project: Apache Drill
Issue Type: Bug
Components: Storage - Parquet
Reporter: Parth Chandra
Assignee: Parth Chandra
In some cases, we see the Parquet reader as the bottleneck in reading from the
file system. RWSpeedTest is able to read 10x faster than the Parquet reader so
reading from disk is not the issue. This issue is to add more instrumentation
to the Parquet reader so speed bottlenecks can be better diagnosed.
