Hi, I'm currently streaming data with nodetool rebuild on 2 nodes, each node is streaming from different location. The problem is that it takes ~7 days to stream 4Tb of data to 1 node, the speed on each side is ~150Mbit/s so it should take around ~2,5 days . Although there are resources on the destnodes and in the source regions. I've increased stream throughput, but its only affects outbound connections. Tested with iperf the bandwidth is 600Mibt/s from both sides. Last week i've changed the CS from ST to LC because of huge sstables and compaction of them is still ongoing. How does rebuild command works ? Does it calculate the range then request the needed sstables from that node and start streaming ? How is it possible to speed up the streaming ?
Vitali.
