we have a Cassandra set up running with 4 nodes with Reflicationfactor:2 and
OrderPreservingPartitioner as partitioner but we have not provided InitialToken
values.
Could some one suggest me what is best way to balance my cluster because some
of user threads have suggested do not ever run
See the section on Moving or Removing nodes here
http://wiki.apache.org/cassandra/Operations you should also read the
bootstrapping section as that is essentially what you are doing.
AFAIK you should use nodetool move to assign a new token to the nodes. As you
say, loadbalance is not
Lot of memtables means lot of sstables means lot of disk io.

Yes, lots of CFs is bad means lots
It should be simpler than that if the wiki is correct. Search the list
archives or wiki for the small script that calculates what the token should be
for each node. After that it should be as simple as using nodetool move on one
node at a time.

Hi,
I can't test new IndexOperators so I would like to ask you whether new
Cassandra 0.7 sorts the results - i.e. I have an secondary index on age of
user cf and I want to get top 10 oldest users.
Can cassandra do this?
Thanks,
Petr
