Yichi Zhang updated BEAM-8314:
------------------------------
Description:
Seems that in StreamingDataflowWorker we are not able to update the metrics
fast enough to dataflow service, the piling metrics causes memory usage to
increase and eventually leads to excessive memory thrashing/GC. And it will
almost stop the pipeline from processing new items.
