> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Ozone Datanode
> Reporter: Supratim Deka
> Assignee: Aravindan Vijayan
> Priority: Major
> Labels: pull-request-available

>
> applyTransaction is invoked from the Ratis pipeline and the
> ContainerStateMachine
> uses a async executor to complete the task.
>
> We require a latency metric to track the performance of log apply operations
> in the state machine. This will measure the end-to-end latency of apply which
> includes the queueing delay in the executor queues. Combined with the latency
> measurement in HddsDispatcher, this will be an indicator if the executors are
> overloaded.
