The simplest way to build resilient applications
summary
Shows a concrete stack: Java SDK + Restate proxy (single Rust binary) used to implement Durable Execution with live code demos. Demonstrations include automatic retries that resume from a persisted journal (payment created once, subscriptions completed), stateful virtual objects with per-key queues, and awaitable futures for email verification with 1‑day expiry and 5s reminder loop. The demos run, crash and recover as claimed, and a distributed/HA Restate release is announced.
