ok, thank you both for the clarification. So the correct approach would
be to bootstrap the new node and run repair on each of the nodes in the
cluster.
I'm a bit puzzled though, I just tried to increase R to 3 in a cluster
with N=2. It serves reads and writes without issues CL.one. Is the

ahh, I think you may have hit a corner case here.
If the RF still 1 ?

I think your original plan is sound.
1. Up the RF to 4.
2. Add the node with auto_bootstrap true
3. Once bootrapping has finished the new node has all the data it needs.
4. Check for secondary index creation using describe in the CLI to see which

ok, thank you for your time!

Hi,
Since this thread already contains the system setup, I just want to ask
another question:
If you have 3 data centers (DC1,DC2 and DC3) and you have a keyspace where
the strategy options are such that each DC gets one replica. If you only
write to the nodes in one DC1 what is the path the repl

You'll need to either read or write at at least quorum to get consistent
data from the cluster so you may as well do both.
Now that you mention it, I was wrong about downtime, with a two node
cluster reads or writes at quorum will mean both nodes need to be online.
Perhaps you could have an emergen

I would guess more aggressive compaction settings, did you update rows or
insert some twice?
If you run major compaction a couple times on the 0.8.1 cluster does the data
size get smaller?
You can use the "describe" command to check if compression got turned on.

Doing reads and writes at CL=1 with RF=2 N=2 does not imply that the reads
will be inconsistent. It's more complicated than the simple counting of
blocked replicas. It is easy to support the notion that it will be largely
consistent, in fact very consistent for most use cases.

Hi guys,
While creating schema on our cluster today I didn't get any errors even
when some of the hosts in the cluster were unreachable (not the ones in the
same data centre but in another region). cli kept on showing all nodes

Now after this when I did "de
The Cassandra team has been released new version every month last half year.
So I anticipate they will release 1.0.9 before April. Just my forecast:-)

How about to fill zeros before smaller digits?
Ex. 0001, 0002, etc

if your keys are 1-n and you are using BOP, then almost certainly your
ring will be massively unbalanced with the first node getting clobbered.
You'll have bigger issues than getting lexical ordering.
I'd try to rethink your design so that you don't need BOP.

Thanks Aaron for the response. I see those logs.
I had one more question. Looks like sstableloader takes only one directory
at a time. Is it possible to load multiple directories in one call.
Something like sstableloader /drive1/keyspace1 /drive2/keyspace1...
This way one can take adv of the speedu
