This allows customisation and use of specialised features without custom, proprietary software for niche hardware. Some commenters appear to confuse unlike hardware for differences in software.

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. The beauty of persistent memory is that we can use memory layouts for persistent data (with some considerations for volatile caches etc. What about security?

This not only results in cost savings by minimizing hardware requirements but also has the potential to decrease cloud expenses.

Add onto that the yawning chasm between low-end and high-end device performance thanks to chip design factors like cache sizes, and it can be difficult to know where to set a device baseline.

Memory might be durable, but… …it is expected that caches and registers will remain volatile. That means of course that we have to have a way to recover the control plane structure after a crash, and we’ll be trading off slightly longer recovery times while we recreate it, for faster operation in the normal case.

SQL provides a declarative programming interface, below which the system itself can figure out the most effective execution plans based on data size and statistics, layout, compute hardware etc. Once a library of UDFs have been built up of course, they could be reused across computations.

This uses hardware, typically a crystal oscillator, that produces ticks at a very high constant rate regardless of processor speed, power settings, or anything of that nature.
