@penkov/tasks_queue/dist/tasks-pool.d.ts

A lightweight PostgreSQL-backed task queue system with scheduling, retries, backoff strategies, and priority handling. Designed for efficiency and observability in modern Node.js applications.

/**
 * Configuration of a worker pool inside {@link TasksPoolsService}.
 *
 * Pools let applications isolate workloads with different concurrency or
 * polling requirements while still sharing the same queue database.
 *
 * See also {@link DEFAULT_POOL} and {@link TasksPoolsService.registerWorker}.
