> 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.
