Agenda:

1. Disk Balancer feature(HDDS-5713), the major code development is finshied. Next Yiyang will test the function locally.
2. Native ACL discussion
   • Discussed whether directory native ACL will be checked when accessing a file in FSO bucket. The answer is unclear. Need further check ther implementation.
   • Discussed prefix ACL, if multiple prefixs are matches, what's the expected behavior of ACL check, which prefix ACL rule will be used. The prefix ACL which matches the most will be used.
   • Shared the prefix ACL usage. It's used to control the access from different users to differernt hive tables.
3. Discussed HDDS-10385 "Memory leak for thread local usages in OMClientRequest". It's mentioned that there is no memory leak observed in the production cluster with previous ThreadLocal implementation, and a high GC pressure is also observed if ThreadLocal is replaced with create object for each OMClientRequest. A new proposal is made and it's feasibility needs further check.
