-------------------------------------------
Damn.
> Bulk loading snapshots creates RF^2 copies of the data

> Key: CASSANDRA-4756
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4756
> Project: Cassandra
> Issue Type: Improvement
> Affects Versions: 1.2.0 beta 1
> Reporter: Nick Bailey
>
> Since a cluster snapshot will contain rf copies of each piece of data,
> bulkloading all of those snapshots will create rf^2 copies of each piece of
> data.
> Not sure what the solution here is. Ideally we would merge the RF copies of
> the data before sending to the cluster. This would solve any inconsistencies
> that existed when the snapshot was taken.
> A more naive approach of only loading one of the RF copies and assuming there
> are no inconsistencies might be an easier goal for the near term though.
