    How does this solution differ from AutoMQ and WarpStream? I’ve worked with one of them, and it is indeed a serverless solution built on top of S3.

    As far as I know, Kafka itself already supports offloading some data to S3 for long-term storage.

    Based on the articles—which I didn't fully grasp—I’m wondering if there are additional benefits mentioned, such as multi-region distribution (though I find it hard to imagine how that would be implemented).

      It’s built for Cloudflare ecosystem, IMO using K2 on its own doesn’t make sense. I’ve worked with a startup that uses Cloudflare for everything except for Kafka. If K2 were to exist back then, I’m pretty sure they would have used it.

      Kafka also has inkless with diskless topics that run off object storage!
