Latency and Availability - Temporal Nexus

View Markdown

Nexus latency and availability in Temporal Cloud:

• SLOs and the SLA - Nexus operations (for example, RespondWorkflowTaskCompleted, PollNexusTaskQueue, RespondNexusTaskCompleted, and RespondNexusTaskFailed) have the same latency SLOs as other Worker requests in both caller and handler Namespaces. For contractual coverage, see the Temporal Cloud SLA.
• 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.
