DC aware failover

[CPC]

Hi,

We want to implement DC aware failover policy. For example if application
could not reach some part of the ring or if we loose 50% of local DC then
we want our application automatically to switch other DC. We found this
project on GitHub  https://github.com/adejanovski/cassandra-dcaware-failover
but we don't know whether it is stable and used in production. Do you know
about this project or do you know other projects that provide same kind of
functionality.

Thanks...
