SUPPORT, STABILITY, and DEPENDENCY INFO

Temporal Nexus is now Generally Available. Learn why you should use Nexus in the evaluation guide.

Nexus latency and availability in Temporal Cloud:

• SLOs and SLAs - Nexus operations (for example, RespondWorkflowTaskCompleted, PollNexusTaskQueue, RespondNexusTaskCompleted, and RespondNexusTaskFailed) have the same latency SLOs and availability SLAs as other Worker requests in both caller and handler Namespaces.
• Nexus metrics - SDK and Cloud latency metrics for monitoring Nexus performance.
• Cross-Namespace connectivity - Traffic routes through a global mTLS-secured Envoy mesh. Same-region Namespaces have low latency; cross-region latency varies by provider. See secure connectivity.
