      If you are looking for a master-master replication I can say that
      Percona Xtradb cluster works very well.&nbsp; There are a few extra
      settings that need to be in my.cnf pertaining to wsrep but not too
      bad to set up, certainly not painful.&nbsp; I am currently running a 3
      master cluster for an eCommerce site. &nbsp; I can not speak to cross
      data center replication though as all three are racked above one
      another.&nbsp; MMySQL is pretty quick but can it not compare to MongoDB
      or CouchBase.&nbsp; I have used many SQL db and a few NoSQL and the
      NoSQL are much faster, easier to scale, and just plain more fun.&nbsp;
      My opinion and of course YMMV<br>

                    <br>
                    Hi All<br>
                    <br>
                    &nbsp;<br>
                    <br>
                    Does any one have experience with FreeSWITCH Core
                    and Cassandra Database. Sounds like Cassandra (<a
                      moz-do-not-send="true"
                      href="http://cassandra.apache.org/">http://cassandra.apache.org/</a>)
                    have a better replication system. This will help to
                    distribute freeswitch across multiple data centers
                    and provide a better fail over system.<br>
                    <br>
                    &nbsp;<br>
                    <br>
                    Any feedback ? Thank you in advance.<br>
                    <br>
                    &nbsp;<br>
                    <br>
                    Thanks<br>
