Github user phrocker commented on the issue: https://github.com/apache/accumulo/pull/260 Have you addressed Josh's concern about RPC calls? Further if you profile the context switching involved with the threads migrating is the net benefit better than stopping the scan entirely? It stands to reason that a long running scan will continue to be long running. Finally, since this is mostly uncooperative yielding, is there any way to measure the fringe conditions, as per metrics that Josh alluded to? Such as average time before forced yield, etc? I think if you're baking this into SKVI that should be an expectation of any initial implementation to address the concern of provability.
