The simplest way to build resilient applications
summary
Restate is a durable execution engine demonstrated with Rust that persists a journal of each function’s executed steps so retries resume exactly where they left off; the subscription demo shows a failed Netflix call retried to completion and the client eventually receives the final result. It exposes durable futures like an awakable ID sent in the email link and durable timers that survive process kills, plus per-key queueing for virtual objects (entity-scoped KV) for exactly-once, concurrent-safe state. The system runs as a single binary using RocksDB and a Kafka-style log with a replicated state machine.
