Do you have any TODO work item on this (or after vectored I/O is merged)? > Add metrics support for parquet file reader > ------------------------------------------- > > Key: PARQUET-2374 > URL: https://issues.apache.org/jira/browse/PARQUET-2374 > Project: Parquet > Issue Type: Improvement > Components: parquet-mr > Affects Versions: 1.13.1 > Reporter: Parth Chandra > Priority: Major > > ParquetFileReader is used by many engines - Hadoop, Spark among them. These > engines report various metrics to measure performance in different > environments and it is usually useful to be able to get low level metrics out > of the file reader and writers. > It would be very useful to allow a simple interface to report the metrics. > Callers can then implement the interface to record the metrics in any > subsystem they choose. -- This message was sent by Atlassian Jira (v8.20.10#820010)
