Astyanax is a Java Cassandra client library. Astyanax was the son of Hector in Greek mythology. As such, Astyanax is a refactoring of Hector into a cleaner abstraction for the connection manager and a simpler API.

Astyanax implements a set of common cassandra use cases as recipes.
|Distributed-Row-Lock||Lock semantics on a single row within a column family.|
|Uniqueness-Constraint||Similar to Distributed-Row-Lock except for that the lock has no TTL and can be used to check whether a row already exists.|
|Multi-Row-Uniqueness-Constraint||Extension of Uniqueness-Constraint across multiple column families which checkes whether an entire set of rows is unique.|
|Chunked-Object-Store||Optimizes chunking and parallel upload and download of large files. Reduces heap pressure caused by storing very large objects that are accessed with high concurrency.|
|All-Rows-Query||Iterate through all rows in a single column family by properly parallelizing and paginating.|
|Message-Queue||Experimental message queue. The queue supports triggers for recurring events.|
