While hardware such as intelligent SANs, Solid State Disk, and other advancements have helped speed things up, wasted space in index can translate to wasted space in the buffer pool as well as wasting more I/O. There are exceptions to every rule or best practice. With modern hardware, the cost estimation of 5 is outdated.

Andrew Ng , Christopher Ré , and others have pointed out that in the past decade, we’ve made a lot of progress with algorithms and hardware for running AI. Our current set of AI algorithms are good enough, as is our hardware; the hard problems are all about data. Is special-purpose training to fine-tune a model’s behavior an option?

A data pipeline is a software which runs on hardware. The software is error-prone and hardware failures are inevitable. In certain scenarios exactly-once semantics is possible but the best you can do is at-least-once or at-most-once. If tuned for performance, there is a good change reliability is compromised - and vice versa.
