Thanks for that.
If it is a known issue I will leave it be as everything is working fine without
it. Have no intention of deploying on OSX, was more that seeing the error
puzzled me some what.

I see what you're saying. I was able to control write latency on mysql
using insert vs insert delayed (what I feel is MySQLs poor man's eventual
consistency option) + the fact that replication was a background
asynchronous process. In terms of read latency, I was able to do up to a

One difference between Cassandra and MySQL replication may be when the network
IO happens. Was the MySQL replication synchronous on transaction commit ? I
was only aware that it had async replication, which means the client is not
exposed to the network latency. In cassandra the network latency

The setup is 10.11.6.9 as the seed and the other three nodes
bootstrapped. I attached two cassandra.yaml files, the config of the
seed, and the config of one of the cluster nodes.

What replication strategy did you use? how does the ring look? were the newly
added nodes bootstrapped? is 1 or more nodes listed as a seed?
Lots of questions. but maybe you could post your cassandra.yaml here and we
can take a look at it.
The output of nodetool ring would also be good.

At the risk of repeating the previous conclusions:
(a) This configuration obviates the need for a patch that I had posted
earlier. This is a good thing.
(b) The reported latency(@Sasha) is less than ordinary latencies in EC2. The
reasons behind this are not well understood. However I wouldn't look

Thanks Aaron!
Unless no one on this list uses EC2, there were a few minor troubles end of
last week through the weekend which taught me a lot about obscure failure
modes in various applications I use :-) My original post was trying to be
more redundant than fast, which has been by overall goal fr
beta versions will be available from releases repo.
You can help validate the poms when I call the release vote.

You can't route traffic over private ips across data centers.this is the
point of the patch.

one last doubt is pending after reading your document:

possible to have internal network of nodes in each data center talking over

Chaps,
We're using 0.7.4 here and aren't ready to go to 0.8 just yet. If I do
apt-get install cassandra=0.7.4 on a clean machine it appears to be

CQL rocks in so many ways.
Is 0.8.0-beta1 available in apache's maven repository?
And if not, why not?

I am not really deep into 0.6.x configuration but what is the listening address

It does seems a bit overkill.
server2 should be pointing to server1 after server1 is online and in
the logs is accepting thrift connections. in what you've pasted
below, you show that server2 is connecting to server2 ... not server1.

Hi,
I was testing the multithreaded compactions and with 2x6 cores (24 with HT)
it does seem a bit crazy with 24 compactions running concurrently.
It is probably not very good in terms of random I/O.
As such, I think I agree with the argument in 2191 that there should be a
config option for this.
