Actor request concurrency and state changes saves
❓type: question
Is there any available documentation on how actors handle multiple concurrent actions/websocket messages? I'm thinking of how on durable objects there's documentation on input/output gates inhttps://blog.cloudflare.com/durable-objects-easy-fast-correct-choose-three/ or how its possibl to call https://developers.cloudflare.com/durable-objects/api/state/#blockconcurrencywhile if you want only one thing to be processed.
Especially since with actors you're not controlling a kv/sqlite database yourself but serialize the whole state map (either at the end of an action or throught https://www.rivet.dev/docs/actors/state#state-saves), I'd love to understand a bit better how/if actors handle multiple concurrent requests and how rivet decides what to serialize when.

When multiple clients access the same storage concurrently, race conditions abound. Durable Objects can make it easier. We recently rolled out improvements to Durable Objects that automatically correct many common race conditions while actually making your code faster.
Cloudflare Docs
The DurableObjectState interface is accessible as an instance property on the Durable Object class. This interface encapsulates methods that modify the state of a Durable Object, for example which WebSockets are attached to a Durable Object or how the runtime should handle concurrent Durable Object requests.
Rivet
Actor state provides the best of both worlds: it's stored in-memory and persisted automatically. This lets you work with the data without added latency while still being able to survive crashes & upgrades.
Build and scale stateful backends. Rivet Actors is a library for long-lived processes with durable state, realtime, and scalability. Easily self-hostable and works with your infrastructure.
