   @VicoWu we are looking to improve this documentation in the coming weeks as we move most of the docs under the documentation section of https://pinot.apache.org/. Stay tuned.
   
   You are right that the wiki link you pointed to provides info on the high level operation aspects. Couple of aspects of Multitenancy that you might be interested in:
    1. Managing the multi-tenant cluster: i.e., from the controller point of view. For more info on this you can review code in PinotTenantRestletResource.java and PinotHelixResourceManager.java as to how the mappings are managed etc. 
   2. Serving multiple tables on servers: this deals with more of the runtime isolation aspects of Multi-tenancy. We currently have CPU isolation between tables - review code in PriorityScheduler.java
   
   Hope this helps. Feel free to reach out if you have more specific questions.
