Is there any document that describes why indexing and querying performance is better at SolrCloud compared to older versions of Solr?
I was examining that architecture to use: there will be a cloud of Solr that just do indexing and there will be another cloud that copies that indexes into them and just to querying because of to get better performance. However if I use SolrCloud I think that there is no need to build up an architecture such like it.
