Piyush Goyal updated FLINK-12680:
---------------------------------
Description:
Currently Flink metric system supports counter, gauge, histogram and meter. For
cases which involve measuring the latency of short-term events (such as request
latency in the context of 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.
