CLUSTER_COORDINATION

public static final String CLUSTER_COORDINATION

Important management tasks that keep the cluster from falling apart. This thread pool ensures cluster coordination tasks do not get blocked by less critical tasks and can continue to make progress. This thread pool also defaults to a single thread, reducing contention on the Coordinator mutex.
