A cluster worker used by a poolifier
ClusterPool.When this worker is inactive for more than the given
maxInactiveTime, it will send a termination request to its main worker.If you use a
DynamicClusterPoolthe extra workers that were created will be terminated, but the minimum number of workers will be guaranteed.Author
