What I'm getting at is what is the underlying tech handling push to clients?
Reading further I see that the graphql libraries handle subscriptions via websockets. But elsewhere in this github I was seeing firebase. So it's a little confusing. Websockets are pretty ubiquitous now but but from what I understand maintain a tcp connection to the server. That has scalability implications.
I think you were probably looking at docs/sample-code for a firebase auth integration.
Hasura GraphQL subscriptions are over websockets. This post is a benchmark that should address those scalability concerns. It’s about getting to 1M concurrent active websocket connections.
