   This is essentially a "read only" tserver except that this process would not be tied to specific tablets.  I love the idea of separating the scans running iterators that are on the more expensive side into separate processes to avoid churn within the accumulo tservers.  The concept is relatively simple.  The trick is doing load balancing appropriately.
   
   On thought is to allow something like Kubernetes to manage instances of these and push the load balancing to an ingress controller.  Something simple baked into accumulo would be great, but appropriate hooks to determine the health and load on one of these processes could be useful.
   
   An additional thought to keep in mind is the ability to embed this server process in something else (e.g. a webserver or perhaps a separate microservice).  Being able to run standalone or embedded would be desirable.
