Hello,
We are trying to add new nodes to our *6-node* cassandra cluster with
RF=3 cassandra version 1.0.11. We are *adding 18 new nodes* one-by-one.
First strange thing, I've noticed, is the number of completed
MigrationStage in nodetool tpstats grows for every new node, while
schema is not c
So what solution should be for cassandra architecture when we need to make
Hadoop M\R jobs and not be restricted by number of CF?
What we have now is fair amount of CFs (> 2K) and this number is slowly
growing so we already planing to merge partitioned CFs. But our next goal is to
run hadoop ta
ree lunch by just
scaling out in terms on new CFs. I would imagine that under the
covers, the layout of Cassandra has a sweet spot of a smallish number
of CFs (i.e. 10s), but these can practically have as many rows as you
like.

available in 1.x and supposed to require less free disk space (but
comes at price of I/O).

I didn't track mailing list since 1.1-rc is out and know i have several

high load, running compactions and clean-ups? Is it faster then 1.09?
2) If i what to use hector as cassandra client which version is better
