*Qihoo* - Plan to use NVME as the read/write cache in each DN. - Shared the POC code about how to reduce multiple serialization and deserialization of OMRequest objects. Will submit a patch later. *Cloudera* - Update of Hbase on Ozone progress - Short circuit read support in Ozone design https://issues.apache.org/jira/browse/HDDS-10685. *Shopee* - 1.4.1 release is discussed and kicked off in the community. - Looking forward to the performance data of gRPC zero copy improvement. - Current OM table cache uses the desalinated data as key and value. To reduce unnecessary serialization and deserialization of objects when accessing table cache, a new type of cache which holds Java objects is suggested. *DiDi* - OM long GC (>60s) doesn't appear again after tuning the CMS GC parameters. - EC data writing is a little bit slow. Suggested apply following two patches https://issues.apache.org/jira/browse/HDDS-9911 https://issues.apache.org/jira/browse/HDDS-9912 - Tested and shared the follower read performance. https://docs.google.com/document/d/1xVkaQYDXJmztETJVZQHkkij_j8j6MGQ4XB8ehathhG8/edit#heading=h.r9ym4lnx88xm
