Pure flour-power. Hearty enough to carry you through lunch.
Summary
This technical blog post explores the possibility of replacing cache services with databases, examining why caches are used (primarily for low-latency data access), current limitations of databases in achieving cache-like performance, and the author's perspective that while progress is being made, databases cannot fully replace caches yet. The article discusses cache patterns, database limitations, and the trade-offs between consistency and performance.
Key quotes

I am talking about typical use cases where we use a cache along with the db (cache aside pattern), where the application always talks with cache and database.
tl;dr we are still not there, yet.
Why do we even use caches?
