We use ZK for some incrementing counters and this is method that does it (this is wrapped in a Thrift call) :
That's good to know. I've often seen high latency between availability zones.BTW, does anyone from Digg patrol the list? I'm really interested in some additional the implementation of atomic counters with ZooKeeper.On Mon, Mar 29, 2010 at 1:58 PM, Joe Stump <firstname.lastname@example.org> wrote:I can attest Cassandra works fine over inter-DC connections. We have ~20 nodes spread across three Amazon "Availability Zones". I know Digg is doing bi-coastal Cassandra as well without issues.
