SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Restate provides a durable execution framework that journals all handler side effects and replays them after failures, enabling reliable, fault-tolerant applications.

Core Features & Use Cases

Durable execution for services, virtual objects, and workflows with automatic retries and state management.
Journaled actions, durable timers, and reliable service calls to coordinate complex distributed logic.
Use case: build resilient microservices, long-running processes, and event-driven pipelines with exactly-once semantics.

Quick Start

To start exploring Restate, install the Restate Server and CLI locally, register a deployment, and invoke a sample service through the UI to observe durable execution in action.

FAQPage Schema

How does durable execution improve fault tolerance in microservices?▼

Durable execution ensures fault tolerance by journaling handler side effects and replaying them after failures. This approach enables resilient microservices, long-running workflows, and event-driven pipelines with exactly-once processing semantics.

How do I build reliable service calls and durable timers for long-running workflows?▼

You build reliable service calls and durable timers by implementing your logic with the Restate SDK. Developers must wrap external calls in ctx.run and rely on deterministic handlers to ensure journaled actions and state meet durability guarantees.

Can I use virtual objects and workflows for stateful distributed logic?▼

Yes, virtual objects and workflows provide durable building blocks like state and timers for stateful distributed logic. They enable fault-tolerant orchestration by journaling handler side effects, ensuring resilient applications with exactly-once semantics.

What's the best way to start exploring durable execution locally?▼

To start exploring durable execution, install the Restate Server and CLI locally, register a deployment, and invoke a sample service through the UI. This allows you to observe journaled actions and fault-tolerant orchestration in action.

Why do deterministic handlers matter for durable execution guarantees?▼

Deterministic handlers matter because they ensure journaled side effects replay consistently after failures. Developers must implement logic using the SDK and wrap external calls in ctx.run to reliably meet durability and fault-tolerance guarantees.
