--------------------------------
Summary: In ContainerStateMachine, share the executor threads
between the containers
Key: HDDS-5355
URL: https://issues.apache.org/jira/browse/HDDS-5355
Project: Apache Ozone
Issue Type: Improvement
Components: Ozone Datanode
Reporter: Tsz-wo Sze
Assignee: Tsz-wo Sze
{code:java}
//ContainerStateMachine
private ExecutorService getCommandExecutor(
ContainerCommandRequestProto requestProto) {
int executorId = (int)(requestProto.getContainerID() % executors.length);
return executors[executorId];
}
{code}
In the code above, different containers having the same remainder (mod
executors.length ) will use the same executor even if some other executors are
idle. Ideally, different containers should use a different executor if there
are executors available.
