I am in the process of migrating from a single Solr instance, with multiple cores, to the SolrCloud. My product uses cores to physically separate our customers' data: CocaCola has its own core, Pepsi has its own, etc. I want to keep that physical separation but of course I need horizontal scaling now. From my readings of the docs, separation in the SolrCloud is provided by Collections (if a Collection is a logical index). However each Collection is its own Node. Creating a Node for every customer seems wrong somehow.
There are small and large customers - so 5 small customers could share the same Node. Some customers are big enough to need their own Node(s). So my question is - can I create multiple Collections within one Node (the multiple Cores in a single Solr instance model)? If not, are there special risks to having a cluster with 200 Nodes? The difference seems to be ... is it better to have one massive JVM per physical server, or lots and lots of small ones? Thanks! running 4.10 now but considering upgrading to 5.x -- View this message in context: http://lucene.472066.n3.nabble.com/Migrating-from-solr-cores-to-collections-tp4217346.html Sent from the Solr - User mailing list archive at Nabble.com.
