- `workerChoiceStrategy` (optional) - The worker choice strategy to use in this pool:
- `WorkerChoiceStrategies.ROUND_ROBIN`: Submit tasks to worker in a round robin fashion
- - `WorkerChoiceStrategies.LEAST_USED`: Submit tasks to the worker with the minimum number of running and ran tasks
- - `WorkerChoiceStrategies.LEAST_BUSY`: Submit tasks to the worker with the minimum tasks total execution time
+ - `WorkerChoiceStrategies.LEAST_USED`: Submit tasks to the worker with the minimum number of executed, executing and queued tasks
+ - `WorkerChoiceStrategies.LEAST_BUSY`: Submit tasks to the worker with the minimum tasks total execution and wait time
- `WorkerChoiceStrategies.LEAST_ELU`: Submit tasks to the worker with the minimum event loop utilization (ELU) (experimental)
- `WorkerChoiceStrategies.WEIGHTED_ROUND_ROBIN`: Submit tasks to worker by using a weighted round robin scheduling algorithm based on tasks execution time
- `WorkerChoiceStrategies.INTERLEAVED_WEIGHTED_ROUND_ROBIN`: Submit tasks to worker by using an interleaved weighted round robin scheduling algorithm based on tasks execution time (experimental)
- `workerChoiceStrategyOptions` (optional) - The worker choice strategy options object to use in this pool.
Properties:
- - `medRunTime` (optional) - Use the tasks median runtime instead of the tasks average runtime in worker choice strategies.
+ - `runTime` (optional) - Use the tasks median runtime instead of the tasks average runtime in worker choice strategies.
+ - `waitTime` (optional) - Use the tasks median wait time instead of the tasks average wait time in worker choice strategies.
- `weights` (optional) - The worker weights to use in the weighted round robin worker choice strategy: `{ 0: 200, 1: 300, ..., n: 100 }`
- Default: `{ medRunTime: false }`
+ Default: `{ runTime: { median: false }, waitTime: { median: false } }`
- `restartWorkerOnError` (optional) - Restart worker on uncaught error in this pool.
Default: `true`
Default: `60000`
- `killBehavior` (optional) - Dictates if your async unit (worker/process) will be deleted in case that a task is active on it.
- **KillBehaviors.SOFT**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still running, then the worker **won't** be deleted.
- **KillBehaviors.HARD**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still running, then the worker will be deleted.
+ **KillBehaviors.SOFT**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still executing, then the worker **won't** be deleted.
+ **KillBehaviors.HARD**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still executing, then the worker will be deleted.
This option only apply to the newly created workers.
Default: `KillBehaviors.SOFT`
