Oh, and there’s a scheduler too of course to keep all the plates spinning. On the Cloudburst design teams’ wish list: A running function’s ‘hot’ data should be kept physically nearby for low-latency access. A low-latency autoscaling KVS can serve as both global storage and a DHT-like overlay network.

Of course, these complex properties don't make them "high value added" services. They're still utilities.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated.

Therefore any programming abstraction must be low latency and the kernel needs to be kept off the path of persistent data access as much as possible. Traditional pointers address a memory location (often virtual of course). This means that the overheads of system calls become much more noticeable.

Micro-optimizations are great for keeping performance on track, but it’s critical to have clearly defined targets in mind — measurable goals that would influence any decisions made throughout the process.
