In this section we will talk about the reasons to move RAMEN ( Real-time Asynchronous MEssaging Network) from SSE (Server-Sent Events) to gRPC as the protocol for delivering messages.īefore jumping into that let’s have a quick look at how we built RAMEN using SSE as the underlying protocol. This blog post will cover how we changed our protocol from Server Sent Events (HTTP1.1) to gRPC-based bidirectional streaming (QUIC/HTTP3), the challenges we faced, the final results, and some key learnings. We use our push platform to deliver these messages that power the real-time user experiences as described in our previous post, which we strongly recommend that you review to learn about the details of the architecture before proceeding.

The shortcut keys assigned to the buttons provide a way to construct diagram through keyboard.In our last blog post we talked about how we went from polling for refreshing the app to a push-based flow to build our app experience.Īll our apps need to be synced with real-time information, whether it’s through pickup time, arrival time, and route lines on the screen, or nearby drivers when you open the app. In sequence diagram, an editor appears at the bottom of diagram by default, which enables you to construct sequence diagram with the buttons there.
