As no one knows (because no one gives a fuck), GoDDD is my implementation of Event Sourcing in Golang. I was really anoyed with this implementation. Normaly, a Domain object called on a mutation method should emit an event that is applied on itself after being saved in an event stream. For this to work properly : The event stream should receive an event that have a specific (known) type (let’s say Event); The domain object should be able to received the event name and the event payload to mutate its state; These two requirements are contradictory because the event payload is of a different structure every time.…

Today I was thinking about rustenstore (you don’t know what it is but who cares ? No one is reading this blog) and how to send the eventstreams to the clients. I told myself that using GRPC was a great idea to decrease connect/disconnect rate between the client and the server. However, a way better idea came just after. Why not just use a TCP connection ? After all, my eventstreams a binary file, so lets send their binary content through the TCP connection.…
