Brian Hess commented on CASSANDRA-9304:
----------------------------------------
[~Stefania] have you re-run the benchmark that [~dkua] performed above (or something similar)
- specifically, comparing the "old version" to this new version (and to the cassandra-unloader
(https://github.com/brianmhess/cassandra-loader))? What performance improvement do we see?

be to parallelize reading and writing (write one page of data while fetching the next).
