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

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
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.

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.

Hi, All,
We plan to upgrade Cassandra from 2.0.17 to 2.1.11 (the latest stable release
recommended to be used in the product environment) in our product.
Currently we are using Astyanax 1.56.49 as Java client, I found there are many

While Astyanax 2.0 is still beta, I think you will find it provides a very
good migration path from the 1.0 thrift based version to the 2.0 native
driver version. Well worth considering if you like the Astyanax API and
functionality. I know of multiple DataStax customers planning on using it
