Yes, I personally have configured it to perf= orm a repair once a week, as the GCGraceSeconds is at 10 days.

This is also what's in the manual=A0 http://wiki.apache.org/cassandra/Oper= ations#Repairing_missing_or_inconsistent_data=A0(point 2)

<= blockquote class=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1px= #ccc solid;padding-left:1ex"> Hello

I have follow question, if we Read and write to cassandra clas= ter with QUORUM consistency level, does this allow to us do not call nodeto= ol repair regular? (i.e. every GCGraceSeconds)
