serviceHandle
EXPERIMENTAL API: Advanced API to invoke a Restate service from the ingress with full control.
Create a handle that provides advanced invocation capabilities including:
- Async request handling with CompletableFuture
- Invocation options such as idempotency keys
- Fire-and-forget requests via
send() - Access to full Response metadata
Client client = Client.connect("http://localhost:8080");
// Use call() with method reference and wait for the result
Response<GreetingResponse> response = client.serviceHandle(Greeter.class)
.call(Greeter::greet, new Greeting("Alice"));
// Use send() for one-way invocation without waiting
SendResponse<GreetingResponse> sendResponse = client.serviceHandle(Greeter.class)
.send(Greeter::greet, new Greeting("Alice"));
