### Describe the enhancement requested It would be nice to have per-filesystem stats to better analyze how filesystems are used by libraries (such as the Parquet reader). Potentially useful stats: * total number of IO requests issued (one IO request could be one POSIX API call for local filesystems, or one network request for S3, etc.) * total number of IO reads issued * total number of IO writes issued * average size of IO reads * average size of IO writes * approximate quantiles of IO read sizes * approximate quantiles of IO write sizes * average duration of IO reads * average duration of IO writes * approximate quantiles of IO read durations * approximate quantiles of IO write durations (perhaps some of those would be too costly to record, we'll see) ### Component(s) C++ -- This is an automated message from the Apache Git Service.
