there are 2 servers, RF=2, W=1, R=1 ... there is 248G of data on each server.

What consistencyLevel are you inserting the elements? If you do
./bin/nodeprobe -host localhost tpstats on each machine do you see one

One current implementation detail in Cassandra is that it loads 128th of the
index into memory for faster lookups. This means you might have

Hi,
I've build a DB as I've made with 0.4.2 now with this code :
final SliceRange sliceRange = new
SliceRange(limitsChannel[0].getBytes(UTF-8),
limitsChannel[1].getBytes(UTF-8), false, headendsChannelList.size());
SlicePredicate predicateKeys = new
Ok Thanks I've see your post in JIRA it seems to be the saqme problem if I

final SliceRange sliceRange = new SliceRange(limitsChannel[0].
getBytes(UTF-8), limitsChannel[1].getBytes(UTF-8), false,
headendsChannelList.size());
by
