Using the "prefix" option

[denvolok]

  const connection = new Redis(6389);
  const queue = new Queue('foo', { connection, prefix: "PF" });

  new Worker('foo', (job)=>{
      return 'bar';
  }, { connection })

  queue.add('foo', {});

Redis keys created:

1) "PF:foo:id"
2) "PF:foo:meta"
3) "PF:foo:wait"
4) "bull:foo:events"
5) "PF:foo:1"
6) "PF:foo:events"

1. Is it expected to have some keys not prefixed?
2. Also, the job in this case is not processed (waiting). Works without the "prefix" option.

bullmq version - 1.26.5

that is definitely a bug, thanks for reporting it.

@manast investigated the problem a bit. All core classes - Worker, QueueScheduler, QueueEvents extend QueueBase, which have the following code in the constructor:

    this.opts = {
      prefix: 'bull',
      ...opts,
    };

So, if we don't specify "prefix" option for this classes - "bull" will be used.
Seems like "prefix" should be synced somehow between all classes.

As a workaround we can specify the same prefix for all core classes instances

ah ok, I missed that you did not specify the prefix on the Worker class, then it works as expected.
