Or just use= the java driver 2. as is. There's even a query builder light fluent DSL if you don't like cql. Based u= pon your use case description so far, I don't think you need to get too funk= y with your data access layer. Whatever you do, make sure the driver you use supports CQL 3 and the native p= rotocol. Thrift, like BOP, will most likely go away at some point in the fu= ture. -- Colin 320-221-9531 > On Jun 8, 2014, at 8:58 PM, Johan Edstrom wrote: >=20 > Kevin,=20 >=20 > We are about to release 2.0 of https://github.com/savoirtech/hecate > It is an ASL licensed library that started with Jeff Genender writing a Po= jo > library in Hector for a project we did for Ecuador (Essentially all of Ecu= ador uses this). > I extended this with Pojo Graph stuff like Collections and Composite key i= ndexing. >=20 > James Carman then took this a bit further in Cassidy with some new concept= s. > I then a while back decided to bite the bullet and my hatred of CQL and ju= st write=20 > the same thing, it started out with a very reflection and somewhat clunky i= nterface,=20 > James decided to re-write this and incorporate the learnings from Cassidy.= >=20 > - Jeff, James and I all work together.
