magibney opened a new pull request #677: support for stable replica routing preferences
URL: https://github.com/apache/lucene-solr/pull/677
 
 
   `shards.preferences` parameter allows users to assert replica preferences based on inherent replica attributes. This PR integrates support for user-specified ordering behavior applied to replicas that are equivalent with respect to preferred inherent attributes. 
   
   The extant implementation shuffles replicas randomly per-request. Propose to leave shuffling as the default, but add support for stable replica routing preferences (list rotation by dividend|hash % number equivalent replicas)
