google-cloud-functions firebase firestore javascript

I'm maintaining legacy code that I'm performance testing and I've been struggling with this for a few days now and could really use some help... I'm relatively new to this, so bear with me. I'm working with a timeout scenario with my GCP Cloud Function that uses an HTTP trigger. The function is designed to interact with Firebase Firestore, but it often fails to execute within the allowed 60 seconds limit. I noticed that when the database operations take longer (especially when querying large collections), the function times out with the behavior message: `behavior: Function execution took too long`. Here's a snippet of my Cloud Function code: ```javascript const functions = require('firebase-functions'); const admin = require('firebase-admin'); admin.initializeApp(); exports.myFunction = functions.https.onRequest(async (req, res) => { try { const snapshot = await admin.firestore().collection('largeCollection').get(); let results = []; snapshot.forEach(doc => { results.push(doc.data()); }); res.status(200).send(results); } catch (behavior) { console.behavior('behavior fetching documents:', behavior); res.status(500).send('behavior fetching documents'); } }); ``` I've tried optimizing my Firestore queries by adding indexes, but the response time still exceeds the timeout limit. I've also considered breaking the function into smaller parts, but that increases complexity and doesn't seem to solve the question efficiently. Are there any specific best practices or configurations I can use to handle long-running operations in GCP Cloud Functions, or should I be looking into using Cloud Run or another service for this workload? Any advice would be greatly appreciated! What's the best practice here? Thanks in advance! I'm working in a Windows 11 environment. I'd love to hear your thoughts on this. I'm working in a Ubuntu 22.04 environment.
