server2 should be pointing to server1 after server1 is online and in

To be honest, this started after feeding data to cassandra for a while with

Chaps,
We're using 0.7.4 here and aren't ready to go to 0.8 just yet. If I do

Thanks

one last doubt is pending after reading your document:
1. when deploying cassandra across multiple dcs using your patch, is it
possible to have internal network of nodes in each data center talking over
private ip? then I assume the node with public ip will act as coordinator.
But if it goes down
Alternatively you could get the deb file at:
http://www.apache.org/dist/cassandra/debian/pool/main/c/cassandra/
and go for dpkg -i cassandra_0.7.4_all.deb

Hi,
Ok, on each node, I have configured the listen address for cassandra
as the VIP interface (tunXXX). This allows other cassandra instances
to connect ONLY through the VPN network. The listen address is not
configured for the eth0 interface (EC2).
rpc_address is set to 0.0.0.0 so that it can listen
I'm trying to setup a cassandra cluster with 0.7.4 on 4 nodes. I
initially did a single server test that went beautifully with a test
that inserted 16 million rows with no issues. However when I tried to
create a 4 node cluster I've been seeing weird behavior. I seem to be
able to run my same test
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
In my test cluster I manged to jam up a cassandra server. I figure the easy
failsafe solution is to just boot a replacement node, but I thought I'd

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

Also don't forget to use the datatype functions in the cli to match what your

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

few hundred
Done and done. I'm really loving how easy the nuclear option has been (it
