Mingyu - Observer SCM GC pressure(>5s) which causes the leader to transfer. It could be related to Container Balancer. With HDDS-10160 <https://issues.apache.org/jira/browse/HDDS-10160>. Cache sort results in ContainerBalancerSelectionCriteria, the container selection performance has great improvement. Now in every iterator, whole container info will be copied for analysis, which might lead to high GC pressure, when container count is more than 1m. Xi - AWS S3 Lifecycle Configurations is updated with the design document HDDS-8342 <https://issues.apache.org/jira/browse/HDDS-8342> . Review and feedback is welcome. Hongbing - After last time OM GC parameter tuning, the long GC(>60s) disappeared for a while. But this week, it happened again. Currently OM max heap is 128G. Will change ratis server close threshold from current 60s to 120s as a workaround. And will try to get a heap dump to further analyze which are the top objects in the OM heap.
