How can I monitor updates from several Google Classroom courses using Pub/Sub?

I’m trying to use Pub/Sub to catch changes from many Classroom courses without using separate threads. Can anyone suggest a simpler code approach?

def build_notification_config():
    config = {
        "source": {"updateType": "ASSIGNMENT_CHANGE", "courseIdentifier": "COURSE_ID"},
        "destination": {"topicPath": "projects/myproject/topics/courseUpdates"}
    }
    return config

hey try mapping the config dynamically so you avoid extra threads. this way you build each course update config on fly which can make it more flexible. hope it helps!

Hey everyone, I was working on a similar problem not too long ago and ended up taking a slightly different route. I started using a kind of dynamic dictionary to hold the config mappings for each course, which let me tie every course’s unique updates back to its Pub/Sub topic without kicking off separate threads for each. It ended up cleaning up a bunch of the code and management overhead. I even experimented with integrating async functions to listen for messages on each topic, and though it was a bit more complex at first, it really paid off in terms of responsiveness. I’m curious – has anyone tried mixing async with Pub/Sub when handling multiple courses? How did it work out, or did you end up taking another approach? Would love to hear more about your experiences and any tips you might have. Cheers! :blush:

In my experience, managing multiple Google Classroom course updates via Pub/Sub can be streamlined by centralizing your event handling. Instead of spawning a thread per course, I developed a unified dispatcher that evaluates each incoming message and dynamically directs it to the appropriate handler. This approach avoids the complexities of thread management and offers improved scalability. By maintaining a configuration mapping for each course, you can flexibly update and manage subscriptions without major code restructuring. This architecture proved more maintainable and resource-efficient, particularly when dealing with a large volume of simultaneous updates.

hey, i ended up using an async event loop that dispatches msgs from pubsub into a single handler. it helps remove extra threading and simplifying the update flow. works pretty well in my setup.
