------------------------------
Status: Patch Available (was: Open)
> 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
> Priority: Major
>
> 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.
