Does the new scheme still require the node to re-iterate all sstables to build the merkle tree or streaming data for partition level repair and move? The disk IO triggered by above steps could be very time-consuming if the dataset on single node is very large. It could be much more costly than the network IO, especially when concurrent repair tasks hit the same node. Is there any good ideas on it? > Richard. >
