I'm currently working on a project to run our medical device integration through ensemble.
I've noticed a potential problem with the volume of messages . The feed generates around 474K messages daily( average of 1 message per minute per device from 300+ devices).
We currently keep all our other feeds message data for 90 days and purge automatically. From what I can see is that the purge functions in Ensemble are production wide and cannot set it at the Business Operation, Service or Router level.
