Show HN: Restate, low-latency durable workflows for JavaScript/Java, in Rust
Today we announce the availability of open-source Restate 1.0, early access to Restate Cloud, and our Seed funding round led by Redpoint Ventures
Our daily business is now stuff like writing code to recover partial failure scenarios, debugging distributed concurrency issues, or wrangling with infra to get reliable ordered callbacks for an asynchronous task. Restate’s APIs let developers use workflows-as-code semantics and other tools like Durable Promises/Futures or atomic state directly in their functions and (micro)services, rather than needing to refactor and redeploy the application to a workflow system. Can be invoked synchronously (req/resp), asynchronously, delayed Supports idempotency keys and deduplication Can pass an awaitable handle for the result to other processes Has exactly-once semantics between two workflow-as-code handlers
