Learn about Nexus latency and availability

Learn about Nexus limits including rate limits, the maximum number of Endpoints, and handler request timeouts.

Temporal Cloud adds global Nexus Registry, built-in access controls, audit logging, and multi-region connectivity on top of core Nexus.

Use the Nexus Registry to manage Nexus Endpoints.

Nexus SDK V2 replaces the per-primitive Nexus Operation helpers with a single Temporal Operation Handler that supports every Temporal primitive and propagates bidirectional links automatically.

Nexus Services are named collections of arbitrary-duration Nexus Operations that provide a microservice contract suitable for sharing across team boundaries.

Back a Nexus Operation with a Standalone Activity instead of a Workflow, so exposing an Activity through Nexus needs no wrapper Workflow.

Plan an approval Nexus Service and write its data contract before any implementation, so every language shares one definition.

Call the Activity-backed notification Operation from a caller Workflow and complete the approval flow end to end.

Use the Nexus Client Code Generator to turn the approval contract into typed models, validators, and Service definitions for the handler and the caller.

Decide whether each Nexus Operation is backed by a Standalone Activity, a Workflow, or an Entity Workflow.

Implement the approval Nexus Service in Java using TemporalOperationHandler, backed by a Workflow, and run a Worker that hosts it.

Create a Nexus Endpoint for the approval Service, allow caller Namespaces to reach it, and set up credentials for Temporal Cloud.

Call the approval Nexus Service from a caller Workflow in another Namespace using the generated Service interface.

Expose Signal, Query, and Update on the approval Workflow as Nexus Operations using the Nexus-aware Client.

Call the Signal, Query, and Update Operations from a caller Workflow, and start an approval with Signal-with-Start.

Back the notification Nexus Operation with a Standalone Activity instead of a Workflow, with no wrapper Workflow required.

Nexus Operations Management Commands
