Re: Cassandra Java Driver and DataStax
How many Java drivers could you point out?

Re: Cassandra Java Driver and DataStax
You can find a very small list containing Hector and the DataStax driver. Hector was made obsolete by quite a few architecture changes (That I don’t disagree with) Claiming you have a large list of drivers is just dishonest. > On Jun 3, 2016, at 9:16 PM, J. D.
