Questions tagged [astyanax]

Astyanax (deprecated) was a Java Cassandra client. It borrows many concepts from Hector but diverges in the connection pool implementation as well as the client API.

Astyanax has been deprecated, and its last merged PR was in October of 2018.

Astyanax is a client library for the Apache Cassandra NoSQL database. Documentation on using Astyanax can be found at their github wiki page.

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