Re: Cassandra Java Driver and DataStax

[Johan Edstrom]

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.

Re: Cassandra Java Driver and DataStax

How many Java drivers could you point out?
Doesn’t it strike you slightly off that you’d not have a driver for a DB 
in the same project you found the DB?
