Every System is a Log: Avoiding coordination in distributed systems

Building resilient distributed applications requires addressing numerous challenges like failovers, retries, race conditions, and distributed coordination. By leveraging the concept that 'every system is a log', systems like databases, message queues, and locking services can simplify handling state and coordination. Adopting a unified log-based approach can significantly reduce complexity and ensure consistency across distributed operations. Restate offers a practical implementation of this concept, allowing event-driven handlers to manage state and coordination seamlessly, leveraging logs for communication, locking, and state updates.
