Summary

  • Add user-facing behavior for the Namespace write bandwidth limit
  • Explain how the limit scales with APS
  • Define namespace_bandwidth_bytes and namespace_bandwidth_throttled_bytes
  • Add monitoring guidance for write bandwidth usage and throttling
  • Link to External Storage guidance for workloads with sustained large payloads

Why

Temporal Cloud will enforce a per-Namespace write bandwidth limit for sustained write traffic. Customers need to know which operations are affected, how throttling appears, how the limit relates to APS, and how to interpret the associated metrics.

Status

This PR is a draft while https://github.com/temporalio/saas-temporal/pull/8378 remains open and the final capacity settings are pending.

The metric definitions assume the proposed public names namespace_bandwidth_bytes and namespace_bandwidth_throttled_bytes.
