How would you handle third party subscriptions in convex

Hi, I am using convex and trigger to do background task processing and I am looking at trigger's realtime SDK. In some bit of code, they 'subscribe' to changes to the task run like in this example they gave. Was wondering is this safe to do in a convex action? Or would it cause the action to hang indefinitely or eat up a lot of bandwidth? Any advice is very much appreciated thank you! link to the docs: https://trigger.dev/docs/realtime/overview

import { runs, tasks } from "@trigger.dev/sdk/v3";

// Somewhere in your backend code
async function myBackend() {
  const handle = await tasks.trigger("my-task", { some: "data" });

  for await (const run of runs.subscribeToRun(handle.id)) {
    // This will log the run every time it changes
    console.log(run);
  }
}

import { runs, tasks } from "@trigger.dev/sdk/v3";

// Somewhere in your backend code
async function myBackend() {
  const handle = await tasks.trigger("my-task", { some: "data" });

  for await (const run of runs.subscribeToRun(handle.id)) {
    // This will log the run every time it changes
    console.log(run);
  }
}

As long as it uses fetch or you have "use node", i think this would work. Two caveats: actions have a 10 minute timeout https://docs.convex.dev/production/state/limits#execution-time-and-scheduling , and every second waiting counts towards Action Compute pricing https://www.convex.dev/pricing This doesn't sound like a cheap or efficient method. If you could get Trigger.dev to send a webhook to a convex action, that sounds better. Or you could consider doing all of the stuff in Convex 🙂

ah that's what I thought, some of the things I want to do are heavy compute like video/image processing so i thought it might be better to do outside convex and send the result back thanks for the clarification @Lee first time seeing a pattern like this so was wondering if it was something I was unaware about
