Subject [GitHub] accumulo issue #260: ACCUMULO-4643 initial implementation
Date Thu, 01 Jun 2017 12:30:54 GMT
Github user phrocker commented on the issue:
    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. 

If your project is set up for it, you can reply to this email and have your

enabled and wishes so, or if the feature is enabled but not working, please
