Use Cases and Patterns

Examples of common Use Cases and Patterns in distributed systems, implemented with Restate.

Durable Promises/Futures:: An implementation of Promises/Futures that are durable cross processes and failures. Can be used to build simple reliable callbacks, communicate/signal between systems, or to decouple sender/receiver.
State Machines: A state machine with a set of transitions. By building it as a Restate Virtual Object, it has automatic state persistence, and concurrency safety that avoids accidental corruption and race conditions issues.
Payment State Machine: A special state machine example that track a payment process and ensures that processing and cancellations (refunding) always sort out consistently, regardless of concurrency and order of requests.
Sagas: The popular Saga pattern that runs a workflow and tracks compensation actions to reverse partial work in case the workflow cannot complete.
