Hi Hannah, mysql-cluster is a in-memory database.
In-memory is fast. But I dont think you ever be able to store hundreds of Gigabytes of data on a node, which is something you can do with Cassandra. If your dataset is small, then maybe NDB is the better choice for you. I myself will not even touch it with stick any more, I hate it with a passion. But this might depend on the use-case :-) regards, Christian On Tue, Apr 16, 2013 at 12:56 PM, jrdn hannah <j...@jrdnhannah.co.uk> wrote: > Hi, > > I was wondering if anybody here had any insight into this. > > I was running some tests on cassandra and mysql performance, with a two > node and three node cassandra cluster, and a five node mysql cluster (mgmt, > 2 x api, 2 x data). > > On the cassandra 2 node cluster vs mysql cluster, I was getting a couple > of strange results.
