TLDR: It's technically CP, but google claims partitions are so rare people can assume it's CA as well (99.999% available).
I assumed TrueTime bypassed the CAP theorem, but apparently that's marketing bs. It's to ensure something called external consistency, which is important if you want to take consistent snapshots over a distributed system.
- majewsky 8y agoSemi-related soapbox: Can we all please stop saying "CAP theorem" and instead say "CAP rule"? The formulation of this supposed theorem is so vague that it can neither be proven nor disproven.
- logophobia 8y agoIt was proven in 2002, has a formal definition, so I'm going with calling it a theorem. Maybe this'll help: https://mwhittaker.github.io/blog/an_illustrated_proof_of_the_cap_theorem/ https://mwhittaker.github.io/blog/an_illustrated_proof_of_th... ?
