 # Read Replica and Rotator
 
-Read replica enhances the search QPS (Queries Per Second) of the Vald cluster by deploying read-only agents in addition to the regular agents and distributing the requests among them. Read replica is deployed as Kubernetes deployments, and depending on the number of replicas (N), it is faster QPS by approximately 1.7 to 1.8 times * N.

 - Sufficient infrastructure is required for QPS scaling
 
-    Even if read replicas are deployed, QPS will not scale if sufficient resources are not available in the Kubernetes cluster. Specifically, agent resources and read replica resources should be deployed on separate nodes. Vald sets `podAntiAffinity` to ensure that agent resources and read replica resources are deployed on separate nodes as much as possible.
