Hi Dan,
We run RF 2 on RAID0 EBS drives. The reason we use EBS over on-instance
storage is two fold;
Firstly we have a relatively small cluster ( 4 nodes ), so we're quite
sensitive to any AWS issues (at the region level). If we had a larger
cluster then we would definitely use ephemeral storage
Hi Alex,
Can you share what replication factor you're running?
And, are you using ephemeral disks or EBS volumes?
Thanks!

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

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,
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.

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
