Hi community, Now I am optimizing the flink 1.6 task memory configuration. I see the source code, at first, the flink task config the cut-off memory, cut-off memory = Math.max(600,containerized.heap-cutoff-ratio * TaskManager Memory), containerized.heap-cutoff-ratio default value is 0.25. For example, if TaskManager Memory is 4G, cut-off memory is 1 G.
However, I set the taskmanager's gc.log, I find the metaspace only used 60 MB. I personally feel that the memory configuration of cut-off is a little too large. Can this cut-off memory configuration be reduced, like making the containerized.heap-cutoff-ratio be 0.15. Is there any problem for this config? I am looking forward to your reply. Best wishes, LakeShen
