If you want super accurate "counters" a good option available is to to
batching on the client side and then take advantage of CAS. For now
counters for smaller windows of time (think minute not days) should help
with some drift issues.

The complete rewrite of counters in 2.1(which should address the counter
accuracy issues) will still have this limitation. Deleting and recreating
counters is not supported and will continue to not be supported.

Off the top of my head: would 99th percentile latency be improved by using
replication factor 5, assuming you are doing quorum operations..

Hello,
I am doing some academic work with Cassandra 1.1.6 (I am on an older
version because of a bunch of implemented modifications that have been
in the works for a while), and I am wondering if the list can help me
resolve some questions I have.
I am running a cluster of 27 nodes with the foll
Hi Fabrice and Yuri,
Thanks for your questions and answers.
