    Congrats on the launch! Stream/event-based system are really powerful, but they are also just pretty complex, in no small part because the modeling of streams for most people today is really modeling Kafka topic/partitions which has a whole bunch of foot-guns and complexity. Making the individual stream really cheap and easy is a big simplification, especially if flexibly consuming a stream for both ordered and unordered use-cases is made simple. This looks to work for unordered, be curious to see how the managed dividing the work for the mentioned key-based ordering.

      Kafka works the way it does for a reason. I don't see how Cloudflare can avoid the same fundamental limits that Kafka faces.

        Discovering the limits is not trivial though, and they also change as hardware changes?

          Kafka doesn't really hardcode any limits though.
