Events that can currently be listened to:
'full'
: Emitted when the pool is dynamic and the number of workers created has reached the maximum size expected.'ready'
: Emitted when the number of workers created in the pool has reached the minimum size expected and are ready.'busy'
: Emitted when the number of workers created in the pool has reached the maximum size expected and are executing at least one task.'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.'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
