On a second reply I'll provide some docs. We looked at Astynax (Yeah I didn't like the refactor) We looked at spring - "Are you fucking kidding me?" We have done quite a bit of work in the ORM arena.
* I passionately hate the idea of CQL. * So - I told myself, I need to make this work so I never ever have to work with that. See, I liked Big Table, I loved the idea of modeling without constrained and contrived relations. I was even more of a fan combining analytics and adjoining vertices. That said, - Hecate-CQL3 does address all of the above, as well as a Pojo / DAO cache, a Table Cache, a what was changed store. If you actually think you'll be writing enterprise code at speed using a Rowset, sorry, you need a foam helmet. /je On Jun 8, 2014, at 9:05 PM, Colin <colpcl...@gmail.com> wrote: > I wasn't responding as a Datastax employee. > > I have used hector, Achilles and a few others as well.
