---------------------------------
Summary: RocksDB block cache is not shared by Datanode containers
Key: HDDS-5053
URL: https://issues.apache.org/jira/browse/HDDS-5053
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Datanode
Reporter: Lokesh Jain
Assignee: Lokesh Jain
RocksDB block cache is not being shared by Datanode containers. The DN process
uses around 20 GB of RSS after startup and does not release the memory even
though rocksdb is closed for every container.
Replacing the OPTIONS_CACHE in AbstractDatanodeStore with static
ColumnFamilyOptions brings the RSS down to ~3.5 GB after startup.
