Question

A GenAI engineer deploys a RAG chain to a Databricks Model Serving endpoint. The deployment succeeds, but automated CI/CD tests begin sending production traffic immediately and many of the first requests return errors before eventually stabilizing. The team wants a reliable, programmatic way to confirm the endpoint is fully ready to serve queries before routing traffic to it. What should they do?

Accepted Answer

Poll the endpoint's status via the Serving REST API and wait until the endpoint state is READY (and the served entity's deployment state indicates it is ready) before sending traffic.

Answer

Add a fixed 5-second sleep after the create/update call, then immediately begin routing production traffic.

Answer

Enable scale-to-zero on the endpoint so that requests automatically queue until compute is provisioned.

Answer

Increase the endpoint's max provisioned concurrency so more replicas absorb the initial burst of requests.
