Comment 7 Tristan Tarrant 2014-12-23 09:00:26 UTC 
I think we should split this bug in two and mark this issue as resolved
Comment 8 Pedro Ruivo 2015-01-05 11:17:43 UTC 
this is a tricky one. I'm currently work on it but I think the solution I have in mind will solve it.
Comment 9 Radim Vansa 2015-01-05 16:21:22 UTC 
The stale value can be read only for a brief period of time.

Since we want rather *eventual* consistency than guarantee up-to-date reads in crash/join/leave/split-brain scenarios, this issue is not critical to JDG.
Comment 11 Radim Vansa 2015-01-07 08:35:47 UTC 
Any resilience tests had trouble with https://bugzilla.redhat.com/show_bug.cgi?id=1166243 . I need to test this yet further, but it seems that partition handling is behaving as expected, since the cache is allowed to become inconsistent/provide stale data in certain time window.
Comment 13 Radim Vansa 2015-01-09 08:33:31 UTC 
This BZ is related to reading stale data, not inconsistent result of writes. What BZ would you like me to verify?

Described test setup is possible.
