True, the jira refers to Cassandra. I think Abmar has just experimented with it, but it is certainly best if he clarifies it. On the C client, that's a very good point. In one of my reviews I pointed it out, but I couldn't find another comment talking about it. I'm not aware of anyone working on it. We should create a sub-task for it and Abmar could perhaps clarify if he is planning on producing a patch for the C client. Please feel free to add to the jira so that we keep it documented, Gustavo. -Flavio On Nov 24, 2010, at 10:26 AM, Gustavo Niemeyer wrote: Hi Gustavo, I don't know if Abmar was using Cassandra as reference (it doesn't sound like from the jira comments), but I followed the paper. Feel free to double-check it if you have a chance. The description references Cassandra explicitly, which is why I wondered.  But then, his comments down the JIRA mention normal vs. exponential distribution, which means he must certainly be aware of the subtleties. Also, note that it won't replace the current mechanism with phi accrual, but it will enable the use of phi accrual. I'd certainly like to experiment with it at some point.  Phi enables the distinction between "slowing down" and "most likely broken", which is an interesting feature.  It isn't clear from the JIRA if someone is working on the C client, though.  Do you know if there's any conversation regarding this? -- Gustavo Niemeyer http://niemeyer.net http://niemeyer.net/blog http://niemeyer.net/twitter flavio junqueira   research scientist   f...@yahoo-inc.com direct +34 93-183-8828   avinguda diagonal 177, 8th floor, barcelona, 08018, es phone (408) 349 3300    fax (408) 349 3301
