> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode
> Affects Versions: 0.5.0
> Reporter: Shashikant Banerjee

> Labels: Triaged
>
> Currently, the stateMachineData which is the actual chunk data is maintained
> in the stateMachineCache inside ContainerStateMachine. Right now, the cache
> expiry is time based as well sized as per the no of parallel write chunks
> possible in the datanode. In case of optimal throughput, we may need to tune
> to it to a fraction of heap configured for the datanode process.
