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 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.
