First off, full disclosure: contributor, committer, PMC member, and finally, Datastax employee, in about that order chronologically.
All of the drivers, as far as I know, are Apache licensed, just as is Cassandra itself. There is no 'control', there is only momentum, since anyone can fork the code if needed and then perhaps gain the momentum if Datastax loses it. Nobody is locked in to anything, and no sufficient traction has been found to take the momentum away from Datastax yet, because at least in my own admittedly biased opinion, our drivers team has done an excellent job of accepting community feedback and requests. tl;dr don't fix what is not broken On Fri, Jun 3, 2016 at 11:11 PM, Mattmann, Chris A (3980) < chris.a.mattm...@jpl.nasa.gov> wrote: > Thanks Jason for the information - I’m going to continue > researching and hope more people will chime in that are on > the PMC. > > Thank you. > > Cheers, > Chris > > ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > Chris Mattmann, Ph.D. > Chief Architect > Instrument Software and Science Data Systems Section (398) > NASA Jet Propulsion Laboratory Pasadena, CA 91109 USA > Office: 168-519, Mailstop: 168-527 > Email: chris.a.mattm...@nasa.gov > WWW: http://sunset.usc.edu/~mattmann/ > ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > Director, Information Retrieval and Data Science Group (IRDS) > Adjunct Associate Professor, Computer Science Department > University of Southern California, Los Angeles, CA 90089 USA > WWW: http://irds.usc.edu/ > ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > > > > > > > > > > On 6/3/16, 8:33 PM, "Jason Brown" <jasedbr...@gmail.com> wrote: > > > > > > > > >The client-server protocol is well defined in the Cassandra repo, so any > one may implement a client library for any language.
