  • Ryan & the Deno team thanks for this. not that I'm going to use it anytime soon - but yeah having durable objects outside Cloudflare and also self hosted ones means a lot.

  • Seeing something like this reminds me of Kleppmann's blog post: https://martin.kleppmann.com/2016/02/08/how-to-do-distribute....

    celld's README states "Object-storage compare-and-swap ensures that exactly one node owns a cell at a time," but I'm skeptical this actually holds at the point where data is written to storage - I had an AI skim through the code with me, and the actual segment writes looked like plain, unconditional PUTs with no epoch check.

    In many cases, I think using Cloudflare's Durable Objects is probably the right call instead.

  • I recently spun up a simple app for our annual mango tasting event[0] using Cloudflare Workers and Durable Objects.

    It worked really well! Excited to see more options outside of Cloudflare.

  • Could someone explain to me in practice how one would use these to do… a thing? Like a straightforward use case? Having trouble figuring out what these are for

  • what is the difference between celld and Cloudflare Workers open source version workerd?

  • Finally!

    So happy to see support for running durable objects outside of one provider. Upvoted.

    The "durable object" concept has been repeatably demonstrated to be a valuable abstraction.

    "Each object is its own SQLite database, addressed by name and replicated to an S3-compatible bucket you own" -- this concept can take you a long way, both in its power and simplicity.

  • Well that couldn't have been any more timely. Did they know? Were they keeping this in a back pocket for the time?

    And yes, celld is isolates! The very lightweight within v8 isolation boundary. Hence the "very low idle cost". The deno team rolled their own new runtime! This one without deno_core! Shout out to this excellent 2022 post: https://deno.com/blog/roll-your-own-javascript-runtime https://news.ycombinator.com/item?id=35819990 https://news.ycombinator.com/item?id=35819990

    It's super super exciting having an age where many pieces of software can all run with low profiles. Very timely, again, for the unbelievably order of magnitude (and thats 10 to the not 2 to the, for you fellow computer nerds) ish ram crunch we are in. Next up, at some point, ideally we get some v8-like runtimes where we can share libraries across multiple isolates! Separating the shared code from the shared data, so we have multiple instances of the library, seems much harder. (It feels like wasm has some/much promise here and I eagerly await clearer signals that code-sharing while sandboxing is indeed possible)

  • Wonder if this will become common practice from now on ?
