I guess the place to start is the Reference Guide: https://cwiki.apache.org/confluence/display/solr/SolrCloud
Generally speaking, when you start Solr with any sort of Zookeeper, you've entered "cloud mode," which essentially means that Solr is now capable of organizing cores into groups that represent shards, and groups of shards are coordinated into collections. Additionally, Zookeeper allows multiple Solr installations to be coordinated together to serve these collections with high availability. If you're just trying to gain parallelism on a single by using multiple cores, you don't specifically need cloud mode or collections. You can create multiple cores, distribute your documents manually to each core, and then do a distributed search ala https://wiki.apache.org/solr/DistributedSearch. The downside here is that you're on your own in terms of distributing the documents at write time, but on the other hand, you don't have to maintain a Zookeeper ensemble or devote brain cells to understanding collections/shards/etc. Michael Della Bitta Senior Software Engineer o: +1 646 532 3062 appinions inc. “The Science of Influence Marketing” 18 East 41st Street New York, NY 10017 t: @appinions <https://twitter.com/Appinions> | g+: plus.google.com/appinions <https://plus.google.com/u/0/b/112002776285509593336/112002776285509593336/posts> w: appinions.com <http://www.appinions.com/> On Tue, Feb 24, 2015 at 3:21 PM, Benson Margulies <bimargul...@gmail.com> wrote: > On Tue, Feb 24, 2015 at 1:30 PM, Michael Della Bitta > <michael.della.bi...@appinions.com> wrote: > > Benson: > > > > Are you trying to run independent invocations of Solr for every node? > > Otherwise, you'd just want to create a 8 shard collection with > > maxShardsPerNode set to 8 (or more I guess). > > Michael Della Bitta, > > I don't want to run multiple invocations.
