So it has both.</p> <p>Yes you can replicate the Solr nodes and data by increasing the RF </p> <p>So if 2 Solr nodes and you want all the data replicated to both you would have strategy_options={Solr:2}; </p> http://www.datastax.com/support-forums/topic/cassandra-replication-when-using-solr#post-1684 Wed, 18 Apr 2012 17:46:47 +0000 jas 1684@http://www.datastax.com/support-forums/ <p>You might find this other thread helpful:</p> <p><a href="http://www.datastax.com/support-forums/topic/dse-20-solr-and-non-solr-related-content-unavailableexception" rel="nofollow">http://www.datastax.com/support-forums/topic/dse-20-solr-and-non-solr-related-content-unavailableexception</a></p> <p>I'm using two Solr nodes (dse cassandra -s) for both handling Solr queries (via SolrJ client library), and maintaining other non-search related data within Cassandra (via Hector). By putting my own non-Solr related keyspaces in the <code>Solr</code> data center, I managed to get things to work. I have two DSE nodes running, and I want them to be replicas, so I did:</p> <pre><code>update keyspace IsecSecurityTokens WITH strategy_options={Solr:2};</code></pre> <p>I'm not working with Hadoop yet, and I did not want to have additional Cassandra only nodes. I wanted two Solr nodes, that I can also use for non-search related content.</p> <p>Hope this helps,</p> <p>Jeff </p> http://www.datastax.com/support-forums/topic/cassandra-replication-when-using-solr#post-1643 Mon, 16 Apr 2012 22:08:42 +0000 Anonymous 1643@http://www.datastax.com/support-forums/ <p>How should replication be setup when using Solr? The wikipedia demo keyspace is setup with "strategy_options = {Solr:1};".</p> <p>It is my understanding that the Solr nodes only store index data; not the complete set of Cassandra data.</p> <p>Should this have been [{Cassandra:1,Solr:1}];? Or is the Cassandra storage implied?</p> <p>If I wanted two replicas in cassandra would I use "update keyspace wiki with strategy_options = [{Cassandra:2,Solr:1}];"?</p> <p>Can you also have replicated Solr indicies? </p>
