We run between US/EU regions on AWS with more than 45ms latency without any
issues. Just use an appropriate amount of replicas in each datacenter and
make use of the appropriate consistency level (e.g local_quoram)

Just make sure you understand the effect of consistency levels on your
performance. You (probably) don't want to be going over the WAN for reads
etc.
We run across the US/EU AWS regions and don't have any problems with higher
RTT.

When you say you moved from EBS to SSD, do you mean the EBS HDD drives to
EBS SSD drives? Or instance SSD drives? The m3.large only comes with 32GB
of instance based SSD storage. If you're using EBS SSD drives then network
will still be the slowest thing so switching won't likely make much of a

Have you changed the appropriate config settings so that Cassandra will run
with only 2GB RAM? You shouldn't find the nodes go down.

Hi Mike,
We had issues with the ephemeral drives when we first got started, although
we never got to the bottom of it so I can't help much with troubleshooting
unfortunately. Contrary to a lot of the comments on the mailing list we've
actually had a lot more success with EBS drives (PIOPs!). I'd d

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

Hey,
Based on current discussions it looks like it will be in C* 1.1, but won't
be in the default cql package - you'll need to opt into cql3 driver as
there are some incompatible BC changes and they want to give an easier
migration. It will be in the default standard distribution in 1.2.

You can switch the reversed flag on (or off) and use the first key returned
