Subject Re: MySQL Cluster performing faster than Cassandra cluster on single table
Date Tue, 16 Apr 2013 11:16:49 GMT
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
