Sammi - HDDS-10656 <https://issues.apache.org/jira/browse/HDDS-10656> Atomic Key Overwrite and Key Replacement, will build the foundation for auto file converting(3 factor <-> EX) - HDDS-10239 <https://issues.apache.org/jira/browse/HDDS-10239> Storage Container Reconciliation, enabling the possibility of block level recovery. Pony - RATIS 3.1.0 RC2 is under vote. Guohao - HDDS-10985 <https://issues.apache.org/jira/browse/HDDS-10985> EC Reconstruction failed because the size of currentChunks was not equal to checksumBlockDataChunks. Shilun explained that the Reconstruction failure is because one current check is rigid. It will reject a common data failure case to be recovered. Since SCM will retry the same container reconstruction until it succeeds, the disk workload becomes very high when this problem happens with quite a few containers. Hongbin/Shilun - EC performance tuning. Suggest to tune property PIPELINE_PER_VOLUME_FACTOR_KEY by @sodonnel <https://github.com/sodonnel> . - Piloted the JDK 17 on production cluster. Met one performance issue caused by JDK bug JDK-8188055. Detailed information can be found here https://docs.google.com/document/d/1g1h-63fvA-be-clvyVRAHLWehoadCnjNRWyX8Bp-UIU/edit. The problem is resolved by upgrading to a higher JDK 17 version. After the JDK issue is fixed, will continue pilot 17 and the new GC algorithm.
