With very large clusters, it is hard to specify exact node names and it still does not give you fine grained control over how nodes are chosen for a shard. The user should be in complete control of where the nodes are allocated for each collection, shard and replica. This helps to optimally allocate hardware resources across the cluster. Rule-based replica assignment allows the creation of rules to determine the placement of replicas in the cluster. In the future, this feature will help to automatically add or remove replicas when systems go down, or when higher throughput is required. This enables a more hands-off approach to administration of the cluster. This feature is used in the following instances: Apache Solr Reference Guide 6.0 605
