Application Information¶
Architecture¶
Prompt Redis is deployed as statefulset in the Prompt Processing vClusters in the prompt-redis Kubernetes namespace.
The Next Visit Fan Out Service sends fanned out events to Redis Streams. Within Redis Streams a stream is configured for each instrument along with a corresponding consumer group and Prompt Processing is configured with a consumer group to read pending messages. The naming for the streams is instrument:<instrument_name>. LSSTCam for example is instrument:lsstcam
