Chris, We technically do have barebones java client in tree [1] CQL was designed as an open protocol anyone can implement [2]
We really want to see a thriving eco-system for drivers. By making CQL an open protocol vs making it some internally controlled document/code we feel it's the best way to achieve this. I'll throw up as a random example [3]. -Jake [1]: https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/transport/SimpleClient.java [2]: https://github.com/apache/cassandra/blob/trunk/doc/native_protocol_v4.spec [3]: https://github.com/matehat/cqerl On Sun, Jun 5, 2016 at 9:32 AM, Mattmann, Chris A (3980) < chris.a.mattm...@jpl.nasa.gov> wrote: > Hi All, > > Thanks for the replies so far.
