limited opened a new issue #3557: Delivery Service to Cache Assignment Groups
URL: https://github.com/apache/trafficcontrol/issues/3557
 
 
   ## Background
   Edge caches can currently be assigned to delivery services in three ways:
   - By Server Profile
   - By Cache Group
   - By Individual Cache
   
   The mids of the assigned edges are chosen based only on the parent and secondary_parent cachegroup settings. 
   
   ## Problem to Solve
   Create a more flexible method of assigning mid/edge caches to delivery services. This allows users to solve the following problems:
   - Dedicating a subset of caches to particular content providers/CDN services
   - Dedicating a subset of caches to particular content types (i.e. PDL or HTTPS content)
   - Specifying exactly which mid-caches are used for a particular delivery service.
   
   The existing "assign by profile" is not sufficient because servers can only be in a single Profile. This proposal introduces a new Cache Assignment Group, of which a server can be in more than one. Also, there is no existing way to influence the selection of mid-caches on a DS-by-DS basis. 
   
   Will followup with a proposal to the dev list. Also will probably create a Project to track the multiple PRs that will be needed.
