Anyone know if there are any specific outstanding issues running
Cassandra on a ipv6 network (defining cassandra.yaml with ipv6
addresses, communication in cluster between nodes defined with ipv4 and
nodes defined with ipv6 addresses, etc.)?
The only thing I'm aware about so far is using ipv6 ad
Just an update to correct something...
The application hits 10.128.16.111. The last lines of Error #4 suggest
that 10.128.16.110 and 10.128.16.112 where down because Cassandra service
was down on 10.128.16.111 and it could not detect the cluster (I think it
must be gossip related, right???).

Hello,
We are currently running a web application utilizing Cassandra on EC2. Given
the recent outages experienced with Amazon, we want to consider expanding
Cassandra across availability zones sooner rather than later.
We are trying to determine the optimal way to deploy Cassandra in this

Hi Mike,
I'm not sure about all your questions, however you should take a look at
LOCAL_QUORUM for your question about consistency level reads/writes.

an hardware upgrade on the server and increased the max heap size. Now
running fine. Seems that 1.1.1 uses a little more memory, or or data set
just grew ;-)
Thank you for your time!

Yes, I saw LOCAL_QUORUM. The definition I saw was:
Ensure that the write has been written to / 2 + 1 nodes,
within the local datacenter (requiresNetworkTopologyStrategy)
This will allow a quorum within a datacenter. However, I think this means
that if availability zones are racks, that the
Hi Mike,
We've run a small (4 node) cluster in the EU region since September last
year. We run across all 3 availability zones in the EU region, with 2 nodes
in one AZ and then a further node in each AZ. The latency difference
between running inside of and between AZ's has been minimal in our

Hi Alex,
Can you share what replication factor you're running?
And, are you using ephemeral disks or EBS volumes?
Thanks!
