Hi Cyril, According to the documentation ( http://wiki.apache.org/cassandra/Operations#Frequency_of_nodetool_repair), I understand that is is not necessary to repair every node before gc_grace_seconds if you are sure that you don't miss to run a repair each time a node is down longer than gc_grace_seconds.
"*IF* your operations team is sufficiently on the ball, you can get by without repair as long as you do not have hardware failure -- in that case, HintedHandoff is adequate to repair successful updates that some replicas have missed" Am I wrong ? Thoughts ? 2013/4/4 <cscetbon....@orange.com> > Hi, > > I know that deleted rows can reappear if "node repair" is not run on every > node before *gc_grace_seconds* seconds.
