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)
