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).Protected Readonly filePath to the worker file.
