What’s new in Cassandra 1.0: Performance

Over the past year, significant improvements have been made to Apache Cassandra's performance, particularly in read and write performance. The latest version, 1.0, has seen a 40% increase in write performance compared to the previous release, while read performance has improved by an impressive 400%. These enhancements are achieved through various optimizations such as using lighter-weight data structures for representing row fragments from reads and only deserializing the most recent versions of requested columns. Additionally, improvements have been made to intra-node communication efficiency, resulting in a 15% faster non-local operation speed in Cassandra 1.0.
