Cassandra Gets Atomic Batches, Virtual Nodes, CQL Improvements

by Roopesh Shenoy on Jan 03, 2013 |

Cassandra 1.2 was recently released with several improvements such as virtual nodes, atomic batch support, better performance and more.

Following are some of the new features -

Collection types are especially useful to simplify models naturally, since CQL doesn't support JOINs. Atomic batches can be used to avoid having to program for retries and idempotent writes. However, this comes with approximately 30% performance hit and can be turned off if performance is more important. 

Cassandra 1.2 is designed to handle several terabytes of data per node, compared to upto 500 GB disk-space limit recommended in 1.0. 

Cassandra is an open source, Columnar, distributed, NoSQL database written in Java. It was originally developed by Facebook to power their inbox search, and it became an Apache project in 2009. You can read more about Cassandra on InfoQ or refer to the updated official documentation.
