The async tracking tooling identifier is poolifier:<PoolType>-<WorkerType>-pool

Events that can currently be listened to:
'ready'
: Emitted when the number of workers created in the pool has reached the minimum size expected and are ready. If the pool is dynamic with a minimum number of workers is set to zero, this event is emitted when at least one dynamic worker is ready.'busy'
: Emitted when the number of workers created in the pool has reached the maximum size expected and are executing concurrently their tasks quota.'full'
: Emitted when the pool is dynamic and the number of workers created has reached the maximum size expected.'empty'
: Emitted when the pool is dynamic with a minimum number of workers set to zero and the number of workers has reached the minimum size expected.'destroy'
: Emitted when the pool is destroyed.'error'
: Emitted when an uncaught error occurs.'taskError'
: Emitted when an error occurs while executing a task.'backPressure'
: Emitted when all worker nodes have back pressure (i.e. their tasks queue is full: queue size >= maximum queue size).'ready'
