zlzhang0122 updated FLINK-20571:
--------------------------------
Description: Now, flink has provided latency metrics to monitor the
latency, but this function mainly used in debugging contexts rather than in
production contexts because of throughput effect. If we provider an api that
can dynamic open/close this function, then we can monitor the online data
latency and find out the performance bottleneck in time without restart the
job, which maybe helpful. (was: Now, flink has provided latency metrics to
