BullMQ - Group/Job based completion - node.js

Question

I am using BullMQ, Redis and MySQL in a producer-consumer model to process jobs.
I have a producer that looks like this:
const jobOptions = {
removeOnComplete: true, // remove job if complete
delay: 60000,
attempts: 3
};
const sasWorkerProducerService = ({redisConnection}) => {
const queueLogId = async (jobId, logIds) => {
for(const logId of logIds) {
redisConnection.add({
jobId: jobId,
scraperPriceLogId: logId
}, jobOptions);
}
}
return {
queueLogId
}
}
module.exports = sasWorkerProducerService;
And I have a worker service that handles the jobs:
const Bull = require('bull');
const connectQueue = (name) => new Bull(name, {
redis: {
port: 6379, host: 'xxxx', password: 'xxxx'
},
settings: {
maxStalledCount: 5
}
})
module.exports = { connectQueue }
const nameQueue = 'sas-worker'
const cases = await connectQueue(nameQueue)
const initJob = () => {
console.info('job is working!');
cases.process('__default__', 300, processJob);
cases.on('failed', handlerFailure);
cases.on('completed', handlerCompleted);
cases.on('stalled', handlerStalled);
}
initJob()
Notice that the producer sends a jobId as part of the payload. This ID is an identifier that I have generated and stored in a MySQL database. A job represents a batch of items that need to be processed. I don't care about what order the jobs for a batch get completed in.
However, how can I determine once all of the jobs for a given jobId have been completed? I need to do some work after all the jobs have been processed.
I understand the nature of a a producer-consumer model is to do work on an item and forget about it, but how can I do some final, post-processing work for a job after all the items have indeed been processed?
