- `workerChoiceStrategyOptions` (optional) - The worker choice strategy options object to use in this pool.
Properties:
- - `retries` (optional) - The number of retries to perform if no worker is eligible.
- `measurement` (optional) - The measurement to use in worker choice strategies: `runTime`, `waitTime` or `elu`.
- `runTime` (optional) - Use the tasks [simple moving median](./worker-choice-strategies.md#simple-moving-median) runtime instead of the tasks simple moving average runtime in worker choice strategies.
- `waitTime` (optional) - Use the tasks [simple moving median](./worker-choice-strategies.md#simple-moving-median) wait time instead of the tasks simple moving average wait time in worker choice strategies.
- `elu` (optional) - Use the tasks [simple moving median](./worker-choice-strategies.md#simple-moving-median) ELU instead of the tasks simple moving average ELU in worker choice strategies.
- `weights` (optional) - The worker weights to use in weighted round robin worker choice strategies: `{ 0: 200, 1: 300, ..., n: 100 }`.
- Default: `{ retries: 6, runTime: { median: false }, waitTime: { median: false }, elu: { median: false } }`
+ Default: `{ runTime: { median: false }, waitTime: { median: false }, elu: { median: false } }`
- `startWorkers` (optional) - Start the minimum number of workers at pool initialization.
Default: `true`
- `concurrency` (optional) - The maximum number of tasks that can be executed concurrently on a worker. It must be a positive integer.
- `taskStealing` (optional) - Task stealing enablement on idle.
- `tasksStealingOnBackPressure` (optional) - Tasks stealing enablement under back pressure.
+ - `tasksFinishedTimeout` (optional) - Queued tasks finished timeout in milliseconds at worker termination.
- Default: `{ size: (pool maximum size)^2, concurrency: 1, taskStealing: true, tasksStealingOnBackPressure: true }`
+ Default: `{ size: (pool maximum size)^2, concurrency: 1, taskStealing: true, tasksStealingOnBackPressure: true, tasksFinishedTimeout: 2000 }`
- `workerOptions` (optional) - An object with the worker options to pass to worker. See [worker_threads](https://nodejs.org/api/worker_threads.html#worker_threads_new_worker_filename_options) for more details.
