/**
 * @description
 * An in-memory {@link JobQueueStrategy}. This is the default strategy if not using a dedicated
 * JobQueue plugin (e.g. {@link DefaultJobQueuePlugin}). Not recommended for production, since
 * the queue will be cleared when the server stops, and can only be used when the JobQueueService is
 * started from the main server process:
 *
 * @example
 * ```ts
 * bootstrap(config)
 *   .then(app => app.get(JobQueueService).start());
 * ```
 *
 * Attempting to use this strategy when running the worker in a separate process (using `bootstrapWorker()`)
 * will result in an error on startup.
 *
 * Completed jobs will be evicted from the store every 2 hours to prevent a memory leak.
