Internal Server Error in Cloud Run

Google Cloud Serverless Applications
1

I am using Cloud Run with FireStore NoSQL DB. Sometime I need to fetch data for 365 days. As this is NoSQL, I need to short data in CloudRun instance but that instance is getting crashed with internal server error if I am querying too much data maybe more than 15,000 query from cloud run to fireStore DB. I am using NodeJs (Express Server) as backend.

Anyone have any idea if this is limitation of Express and If I rewrite backend using GoLang it will solve this issue and should I consider moving to GKE? I have faced same issue on App Engine as well.

I tried same thing from Cloud VM, it worked. So this is not DataBase problem I believe.

As workaround I am pre-calculating data so this is not a blocker for now but need to be fixed.

Hello @anowar ,

The CPU capacity is the main limitation (Cloud Run). So, you don’t have a service limit, only physical CPU limits.

By default Cloud Run container instances are limited to 1 CPU. You can increase or decrease this value as described in this page.

This might also occur to App Engine due to CPU limitation.

I would highly suggest use a Google Kubernetes Engine so that you can configure the CPU limitation based on your needs.

Thanks.

Thank you for your help.

This is also my understanding. I am re-writing the app using GoLang, lets see if that help if we configure multiple CPU otherwise we will move to GKE

It is definitely possible to raise the number of CPUs and amount of memory per instance in Cloud Run. I don’t know if that will fix this issue, but I wanted to make sure you were aware of that.

Thank You. I tried increasing to bigger instance it didn’t help. I didn’t increase cpu count, thinking nodejs can’t take advantage of it. That’s why we are re-writing application with Golang.

Ah, that makes sense.
