Hi, Here's an SIP for introducing the concept of node roles: https://issues.apache.org/jira/browse/SOLR-15694 https://cwiki.apache.org/confluence/display/SOLR/SIP-15+Node+roles
We also wish to add first class support for Query nodes that are used to process user queries by forwarding to data nodes, merging/aggregating them and presenting to users. This concept exists as first class citizens in most other search engines. This is a chance for Solr to catch up. https://issues.apache.org/jira/browse/SOLR-15715 Regards, Ishan / Noble / Hitesh
