The cache is an incomplete dataset by definition. It’s not a data set, it’s a cache of a data set. You can never ensure you get a clean read of the system state

The cache is an incomplete dataset by definition. It’s not a data set, it’s a cache of a data set. You can never ensure you get a clean read of the system state from the cache because it’s never in sync and has gaps.
- IgorPartola 1y agoWhat about materialized views? CPU cache? Only the Sith deal in absolutes :)
- hinkley 1y agoCPU cache means that the same value read twice will return the same value. Some exceptions for NUMA, and mu[tiple threads. But two reads of a cache cache make no such guarantees. There is a vast number of undiagnosed race conditions in modern code cause by cache eviction in the middle of 'transactions' under high system load.
