runzhiwang updated HDDS-3630:
-----------------------------
Description: Currently, one rocksdb for one container. one container has
5GB capacity. 10TB data need more than 2000 rocksdb in one datanode. It's
difficult to limit the memory of 2000 rocksdb. So maybe we should only use one
rocksdb for all containers. (was: Currently, one rocksdb for one container.
