Jason Brown commented on CASSANDRA-4663:
----------------------------------------
Yeah, I think you are correct here. I didn't look that far up the stack (into
{{RangeStreamer}}), but that will surely parallelize transfers by keyspace.
I've kicked off the tests here:
||trunk||
|[branch|https://github.com/jasobrown/cassandra/tree/4663-trunk]|
|[dtest|http://cassci.datastax.com/view/Dev/view/jasobrown/job/jasobrown-4663-trunk-dtest/]|
|[testall|http://cassci.datastax.com/view/Dev/view/jasobrown/job/jasobrown-4663-trunk-testall/]|
If everything looks good with the tests, I'll rename the ticket to something
more appropriate and commit.

> This is not fast enough when someone is using SSD and may be 10G link. We
> should try to create multiple connections and send multiple files in

> Current approach under utilize the link(even 1G).
> This change will improve the bootstrapping time of a node.
