[ https://issues.apache.org/jira/browse/HDDS-5053?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lokesh Jain updated HDDS-5053:
------------------------------
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.
