Subject Read Repairs
Date Sat, 30 Jul 2011 09:04:20 GMT
I have a 3-node ring at RF=3 that is doing reads & writes. I am using two
types of consistency levels.

   - write ALL,read ONE for one set of column families
   - write QUORUM, read ONE for another set of families

Every day, I have a cron job that runs a nodetool repair on each node. The
nodes are not going down and there are no exceptions in the logs.
And yet, nodetool netstats tells me that the ReadRepairStage is increasing
during the day, for example between the time I started this email and the
time I finished it.

I don't understand how this is possible. Any explanation ?
