Requesting Guidance on Configuring Lock Duration and Max Stalled Count in Bull Configuration.

[Jayshri-Intlon]

Issue:

In my project, I have a job queue named 'entityCreateQueue' that runs periodically to complete certain tasks within a specific timeframe. However, I've noticed that sometimes it generates duplicates shortly after completing a task. To address this issue, I've encountered recommendations to set a 'lockDuration' with a larger value and a 'maxStalledCount' to 0, as mentioned in the references I've consulted. However, I'm uncertain about where and how to configure these settings within my Bull queue in the Nest JS application.

Reference:

• Bull Issue #1591
• BullMQ WorkerOptions

Code snippet

import { RedisConfigService } from '../app/config/redis-config.service';
import type { RegisterQueueOptions } from '@nestjs/bullmq';
import { BullModule } from '@nestjs/bullmq';

const redisConfigService = new RedisConfigService(process.env);
const bullOptions: RegisterQueueOptions = {
  name: 'entityCreateQueue',
  connection: redisConfigService.bullConfig.connection,
};

@Module({
  imports: [
    TypeOrmModule.forFeature([Entity, EntityStatusHistory]),
    BullModule.registerQueue(bullOptions),
  ],
