Piyush Goyal updated FLINK-12680:
---------------------------------
Description:
Currently Flink metric system supports counter, gauge, histogram and meter. For
cases which involve measuring the latency of a certain short-term event (such
as request latency in a connector), none of these metric type is a good fit.
Most metric system supports a timer type which is highly useful in such cases.
Timers are useful for measuring short-duration latencies and the frequency of
such events. All implementations of {{Timer}} report at least the total time
and count of events as separate time series.
Timer type will be a nice addition to the existing metric types in Flink.
