There already is signal on many underground lines, and it’s pretty rare that people are playing things out loud in my experience?

https://en.wikipedia.org/wiki/Sovereign

> The roles of a sovereign vary from monarch, ruler or head of state to head of municipal government or head of a chivalric order. As a result, the word sovereignty has more recently also come to mean independence or autonomy.

London is the third most visited city and Heathrow is the second most popular airport by international visitors. The prospect of being arrested upon arrival there might be a little annoying.

Hey, I work on Restate. There are lots of differences throughout the architecture and the developer experience, but the one most relevant to this article is that Restate is itself a self-contained distributed stream-processing engine, which it uses to offer extremely low latency durable execution with strong consistency across AZs/regions. Other products tend to layer on top of other stores, which will inherit the good things and the bad things about those stores when it comes to throughput/latency/multi-region/consistency.

We are putting a lot of work into high throughput, low latency, distributed use cases, hence some of the decisions in this article. We felt that this necessitated a new database.

Wow, fascinating. I wonder if in a few years every in-game opponent will just be an LLM with access to a game-controlling API like the one you've created.

Did you find there are particular types of tasks that the models struggle with? Or does difficulty mostly just scale with the number of items they need to place?

As discussed in the article, we have built our own storage engine from the ground up, which we did because we believe it will achieve better performance by taking advantage of the features of the system (streaming data, single writer etc) instead of shoehorning it into a DBMS. So, our performance goals are very high throughput (100s of thousands of actions per second, scaling horizontally), with very low latencies (like, 40ms p90 under load for a 3 step workflow)

We haven’t built any client side encryption tools yet. I don’t think it would be particularly difficult to do an MVP. If it’s very important to your use case, come chat to us in Discord? https://discord.com/invite/skW3AZ6uGd

Ah I see what you mean. In this case the handler should complete with a terminal error - we weren't able to finish the task in time. Of course, many types of errors and timeouts are valid application-level results, not transient infrastructure issues. And sadly, tight timeouts push transient issues into application-level issues, and this is unavoidable, I think

Thanks! I'm not familiar with Jobrunr, but we can definitely help with orchestrating async tasks (as well as sync rpc calls), especially if its important that they run to completion

Hey! I managed to get a POC running on Cloudflare workers, I had to make some small changes to the SDK eg to remove the http2 import, convert the Cloudflare request type into the Lambda request type, and add some methods to the Buffer type. I suspect similar things would be needed on Deno platforms. We have it on our todo list (scheduled within weeks not months) to make it possible to import a version of the library that just works out of the box on these platforms. I think if we had someone with a use case asking for it, we would happily build that even sooner - maybe come chat in our discord? https://discord.gg/skW3AZ6uGd

Once http2 stuff is removed, there's nothing particularly odd that our library does that shouldn't work in all platforms, but I'm sure there will be some papercuts until we are actively testing against these targets

Yeah, this is pretty much exactly how we propose its done (restate services are inherently versioned, you can register new code as a new version and old invocations will go to the old version).

The only caveat being that we generally recommend that you keep it to just a few minutes, and use delayed calls and our state primitives to have effects that span longer than that. Eg, to poll repeatedly a handler can delayed-call itself over and over, and to wait for a human, we have awakeables (https://docs.restate.dev/develop/ts/awakeables/)
