| <meta name="description" content="The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. |

| |
| <p>If you encounter a problem with Cassandra, the first places to ask for help are the <a href="#mailing">user mailing list</a> |
| and the <code class="highlighter-rouge">#cassandra</code> <a href="#irc">IRC channel</a>.</p> |
| |
| <p>If, after having asked for help, you suspect that you have found a bug in Cassandra, you should report it by opening a |
| ticket through the <a href="https://issues.apache.org/jira/browse/CASSANDRA">Apache Cassandra JIRA</a>. Please provide as much |
| details as you can on your problem, and don’t forget to indicate which version of Cassandra you are running and on which |
