Thanks, great question!

My strategy was to start out by implementing the underlying storage primitives first, and then look into which transport to implement later. The transport of course can have a large impact on the required storage primitives, but in my case I built it the other way around since I knew what primitives I would need in my applications.

I've been playing with the thought of implementing (parts of) the Kafka API, but I honestly haven't considered the transport that much yet :)
