Restate 1.2: a distributed durable execution engine, built from first principles

Restate 1.2 is a distributed durable execution engine designed to simplify the development of resilient, mission-critical applications such as payment workflows and AI agents by offering high availability and consistency across cloud, on-prem, and regional deployments. Emphasizing a simple programming model, Restate captures all application activities into a reliable log, enabling automatic retries and recovery from failures while maintaining low latency. This version introduces a graphical UI for enhanced introspection and debugging, alongside new features for high-availability deployments, allowing for scalable and fast fail-over capabilities. The architecture leverages a tiered system with a distributed log and consensus algorithm, enhancing efficiency and cost-effectiveness by storing most data in object store snapshots. Restate's flexibility and reliability have garnered positive feedback from users who appreciate its ability to simplify complex distributed systems without the need for extensive infrastructure dependencies.
