      Description

      Following this conversation from the mailing list:
      http://lucene.472066.n3.nabble.com/Proposal-for-new-feature-cold-replicas-brainstorming-td4097501.html

      Should give the ability to use replicas mainly as backup cores and not for handling high qps rate.

      This way you would avoid using the caching ressources (solr and OS) used when routing a query to a replica.
      With many replicas it's harder hitting the solr cache (same query may hit another replica) and having many replicas on the same instance would cause a useless competition on the OS memory for caching.
