*** title: "InMemoryJobQueueStrategy" generated: true --------------- An in-memory [JobQueueStrategy](/current/core/reference/typescript-api/job-queue/job-queue-strategy#jobqueuestrategy). This is the default strategy if not using a dedicated JobQueue plugin (e.g. [DefaultJobQueuePlugin](/current/core/reference/typescript-api/job-queue/default-job-queue-plugin#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. ```ts title="Signature" class InMemoryJobQueueStrategy extends PollingJobQueueStrategy implements InspectableJobQueueStrategy { protected jobs = new Map(); protected unsettledJobs: { [queueName: string]: Array<{ job: Job; updatedAt: Date }> } = {}; init(injector: Injector) => ; destroy() => ; add(job: Job) => Promise>; findOne(id: ID) => Promise; findMany(options?: JobListOptions) => Promise>; findManyById(ids: ID[]) => Promise; next(queueName: string, waitingJobs: Job[] = []) => Promise; update(job: Job) => Promise; removeSettledJobs(queueNames: string[] = [], olderThan?: Date) => Promise; } ``` * Extends: [`PollingJobQueueStrategy`](/current/core/reference/typescript-api/job-queue/polling-job-queue-strategy#pollingjobqueuestrategy) * Implements: [`InspectableJobQueueStrategy`](/current/core/reference/typescript-api/job-queue/inspectable-job-queue-strategy#inspectablejobqueuestrategy)
