http://techblog.netflix.com/2012/01/announcing-astyanax.html * * *What is Astyanax?* Astyanax is a Java Cassandra client. It borrows many concepts from Hector but diverges in the connection pool implementation as well as the client API. One of the main design considerations was to provide a clean abstraction between the connection pool and Cassandra API so that each may be customized and improved separately. Astyanax provides a fluent style API which guides the caller to narrow the query from key to column as well as providing queries for more complex use cases that we have encountered. The operational benefits of Astyanax over Hector include lower latency, reduced latency variance, and better error handling.
