Hi all, One rocksdb for each container in datanode cost too much off-heap memory. There are too choices to handle this: Merge Rocksdb or Remove Rocksdb, the design doc of these two choices: https://docs.google.com/document/d/18Ybg-NjyU602c-MYXaJHP6yrg-dVMZKGyoK5C_pp1mM/edit#. And the jira is https://issues.apache.org/jira/browse/HDDS-3630. I would prefre to Merge Rocksdb, because Remove Rocksdb really is a big work and also need to do some work which could be done by rocksdb. The shortage of Remove Rocksdb is in the design doc. If you have any suggestions, please let me know. Thank you very much.
Thanks, runzhiwang
