shared mongodb with multiple masters that only watch for certain jobs?

[aon108]

Is there a way to configure the Master server to watch only specific jobs on a shared mongodb queue from multiple apps so that you can have multiple master servers doing different things?

right now no, but it's something that will be introduced in later versions.
I'll try to update when I can.

I gave an advise about this use case in the README : you should have 1 app dedicated to handling all the tasks.

I did check out all of the README and was thinking that I could just define a unique taskmap for each Master and they wont try run each others jobs but looking at the code I think this change might get the functionality working, what do you think?

• In the taskQueue.js where it pulls the jobs from the mongodb this.pull
• adding the mongodb query filter to only return the tasks that are found inside the taskMap

const taskTypes = _.pluck(this.taskMap,"taskType");
return this.rawCollection().findOneAndUpdate({ taskType: taskTypes, onGoing: false, dueDate: { $lte: new Date() }}, { $set: { onGoing: true }}, { sort: { priority: -1, createdAt: 1, dueDate: 1 }})

and of course update the jobs counts with the same taskType filter line 93

Yes that's exactly what I had in mind ☺️ but I'd like to avoid underscorejs / lodash, so just use `Object.keys` instead of _.pluck. If you want you can make a pull request :)
