description: Restate is a durable execution platform for building resilient distributed applications, microservice orchestration,
  durable workflows, stateful services, and AI agents. Founded by Apache Flink and Apache Kafka veterans (Stephan Ewen, Igal
  Shilman, Till Rohrmann), Restate ships a single-binary Rust runtime that journals every step of handler execution so code
  survives crashes, restarts, and infrastructure failures. The platform exposes an Ingress API on port 8080 for HTTP invocation
  of services, virtual objects, and workflows (with idempotency keys, async /send semantics, and delayed invocations) and
  an Admin API on port 9070 for deployment registration, service introspection, invocation control (cancel, kill, pause, resume,
  restart, purge), subscriptions, and cluster health. Official SDKs target TypeScript, Java/Kotlin, Python, Go, Rust, and
  Ruby, with first-class integrations for AWS Lambda, Cloudflare Workers, Deno Deploy, Vercel, and Kubernetes (via the restate-operator).
  Restate Cloud is the managed offering with SOC 2 Type I compliance, enterprise SSO (Okta, Google Workspace, Azure AD), HIPAA
  BAAs, and an in-preview client-side journal encryption feature.

- aid: restate-dev:admin-api
  name: Restate Admin API
  description: The Restate Admin API is the HTTP control plane for a running Restate Server, exposed by default on port 9070.
    It manages service deployment registration, lists and introspects services and handlers, controls invocations (cancel,
    kill, pause, resume, restart, purge), manages Kafka and event subscriptions, queries system state via embedded SQL, and
    reports cluster health and version. The Admin API is the surface the Restate CLI and Web UI drive, and an OpenAPI document
    for the running server is available at the /openapi endpoint.

  name: Restate Ingress API
  description: The Restate Ingress API is the HTTP data-plane for invoking services, virtual objects, and workflows running
    on Restate Server, exposed by default on port 8080. Requests follow the path conventions /{ServiceName}/{handler}, /{VirtualObject}/{key}/{handler},
    and /{Workflow}/{workflowId}/run, with JSON bodies. Append /send for fire-and-forget invocations that return an invocation
    ID, pass a ?delay= parameter for delayed/scheduled invocations, and use the Idempotency-Key header for at-most-once semantics
    (responses are cached for 24 hours). The Ingress also brokers Kafka-event-driven handler invocations and exposes per-service
    OpenAPI documents at :9070/services/{ServiceName}/openapi.

- aid: restate-dev:service-protocol
  name: Restate Service Protocol
  description: The Restate Service Protocol is the wire protocol Restate Server uses to communicate with handler endpoints
    implemented in any official SDK. It journals every side-effect (durable steps, RPCs, state reads/writes, sleeps, awakeables)
    so handlers can be replayed deterministically and resume from the exact step they were on when an infrastructure failure
    occurred. Implementations of this protocol are what make a language an official Restate SDK; the shared core lives in
    sdk-shared-core and the protocol definitions in the Restate Server source tree.
