Subject RE: Speeding up "nodetool rebuild"
Date Thu, 31 Mar 2016 21:19:10 GMT
Thanks, is there any way to determine that rebuild is complete.

Based on following line in, it's not logged. So, any other way to check
besides checking data size through nodetool status ? 

            // rebuild is done (successfully or not)

TL;DR add more nodes

If you're encountering a per-stream bottleneck (easy to do if using compression), then having
a higher node count will translate to higher stream concurrency, and greater throughput.

Another thing to keep in mind, the streamthroughput value is *outbound*, it doesn't matter
what you have that set to on the rebuilding/bootstrapping node, it *does* matter what it is
set to on the nodes that are sending to it (
aims to introduce an inbound tunable though).
