How to gracefully close, stop, destroy and restart a locked queue at any time? Are there any examples?

There is no concept of locked queues in BullMQ. Regarding graceful shutdowns here you can find some info: https://docs.bullmq.io/guide/going-to-production#gracefully-shut-down-workers

For a task that declares a unique jobId, how to stop and restart this task without affecting the normal operation of other tasks?

[MrWang6w]

For a running task, it is difficult for me to effectively stop and delete it at any time! I am very distressed, I hope you can help me, thank you!

Currently it is only possible to cancel tasks by TTL in the Pro version. BullMQ does not provide any mechanism to just cancel a task like that: https://docs.bullmq.io/bullmq-pro/observables
A possibility would be to implement a separate cancelation mechanism on top of Redis PubSub... but it is not trivial to do.

const { Queue, Worker } = require('bullmq');

const name = 'my_demo_mq';
const jobId = 'my_demo_mq_123456';
const myQueue = new Queue(name);

const myWorker = new Worker(
  name,
  async () => {
  await asyncActions();

  //Is it supported to change the execution time of the next repeated task at the end of the task after executing the current repeated task?

  job.updateEvery???
  },
  {
    concurrency: 10,
    limiter: null,
  }
);

myQueue.add(
  name,
  { mq: true },
  {
    jobId,
    repeat: {
      every: 60 * 60 * 1000,
    },
  }
);

Is it supported to change the execution time of the next repeated task at the end of the task after executing the current repeated task?

@MyZest is this related to this discussion?

[MyZest]

If the task cannot be ended or stopped while the job task is running, I think if I can expose an API that can update the next scheduled task, then I can use this method to control the stopping and restarting of a task!
