Thanks for the explanation. I think i am at loss trying to understand
the tpstats output.. when does the ReadRepair count get incremented?
- When any read is performed with CL < ALL and RF=3 (or)
- When there is a discrepency?
I have 2 snapshots when i run tpstats and the counts indicate there
we
As explained in the link in my earlier reply, "Read Repair" just means
"a replica was checked in the background," not that it was out of
sync.

Yes Hinted Handoff is enabled. However I don't see any counters
raising against the HintedHandoff in the tpstats.
thanks

Do you see any errors in the logs? Is your HH enabled?

Lets assume we have 3 nodes all up and running at all times with no
failures or communication problems.
1. If I have a RF=3 and writing with QUORUM, 2 nodes the change gets
committed, what is the delay we should expect before the 3rd replica
gets written
2. In this scenario ( no failures e.t.c )
Start with http://wiki.apache.org/cassandra/ReadRepair. Read repair
count increasing just means you were doing reads at < CL.ALL, and had
the CF configured to perform RR.

I have a 12 node cassandra cluster running with RF=3. I have severl
clients ( all running on a single node ) connecting to the cluster (
fixed client - node mapping ) and try to do a insert, update , select
and delete. Each client has a fixed mapping of the row-keys and always
connect to the same
