>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6852
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>            Reporter: Cyril Scetbon
>              Labels: multi-dcs, ranges, repair

> Our environment is as follows :
> - 3 DCS : dc1,dc2 and dc3
> - replicate all keyspaces to dc1 and dc2
> - replicate a few keyspaces to dc3 as we have less hardware and use it for computing
statistics
> We use repair -pr everywhere regularly. FYI, a full repair takes almost 20 hours per
node. The matter is that we can't use "repair -pr" anymore for tokens stored on dc3 concerning
keyspaces not replicated. We should have a way to repair those ranges without doing a FULL
REPAIR everywhere
