SSE on Cloud Run, is it working for anyone ?

[rodmargon]

Hi,

I have built a microservice with SpringBoot for sending push notifications to an angular site . I ma using SseEmmiter class supported by spring ( https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/servlet/mvc... ) and it is working perfectly on my local. 

However , it is seems to not doing anything when the service is deployed in cloud run. There is no error when calling the method sseEmiter.send() ...it is just I am no receiving anything in my client. 

SSE was supossed to be supported on cloud run, attending to this https://cloud.google.com/blog/products/serverless/cloud-run-now-supports-http-grpc-server-streaming , but I have seen similar messages from other posts claiming that is not working . So ... has anyone managed to get SSE on cloud run working ?

thanks,Rodrigo

Hi @rodmargon,

Welcome to Google Cloud Community!

As of the moment, we only have limited support for SSE as examples available are only available for the following:

• Cloud Run gRPC Server Streaming sample application (Golang) 
• Streaming Data from Client to Cloud Run Server using HTTP/1 (Node) 

There's a workaround available through this GitHub feature request link that you may find helpful but it is not a guarantee that this would work.

You may also file a feature request so that our engineers could take a look at this. We don't have a specific ETA but you can keep track of its progress once the ticket has been created.

Hope this helps.
