Joe Stump: "It's a brave new world where N+1 scaling with 7,000 writes per second per node is considered suboptimal performance"

Spotted on the cassandra users list. This was on EC2 large instances, which should put the wind up anyone who thinks you need specialised machinery for anything but extreme performance/scale  tradeoff requirements. For many cases now, it seems you don't need to just pick one.

And check out Joe's startup, SimpleGeo: a scale out geo spatial/location platform running on (I think still) AWS and using Cassandra as the backing database, which a bunch of geospatial software built on top. It is a new world - a startup couldnt have done this even a few years ago, not without a boatload of VC funding for the hardware.
