I've posted the following to the Datastax Java Driver user forum, but no
one has responded, so I thought I'd try here, too.
We have a service that writes to a few legacy (pre-CQL) counter column
families in a Cassandra 2.1.11 cluster. We've been trying to migrate this
service from Astyanax
Lijun,
That is correct. If you have an investment in Astyanax , you'll need to
stay in the 2.0 series. You'll either need to wait until Astyanax is
updated to support 2.1 (if that is going to happen) or migrate to the
datastax java driver.

Eric,
That's really an awful thing for me. I looked into the Astyanax code, the
dependency of Cassandra is still staying on 2.0.12, and seems the community
have no plan to upgrade it to support the newer version of Cassandra. But
whatever, thank you so much for your reply.
Thanks,
Lijun Huang
Thank you Minh,
So it means if I want to use Cassandra 2.1+, any version of Astyanax cannot
be compatible with it? Because we are already using the Astyanax, it maybe
a heavy work to change from Astyanax to Datastax Java Driver.
On Wed, Nov 18, 2015 at 11:52 AM, Minh Do <m...@netflix.
The latest version of Astyanax won't work with Cassandra 2.1+. So you are
better off using Java Driver from Datastax.
