Ask HN: What are the best resources for learning caching strategies?

As a cloud architect, I highly recommend this guide: https://github.com/donnemartin/system-design-primer

All the patterns are there. Fan out for buffering writes to increase the amount that can be cached for reads, write through cache, write back cache, etc.

Specifically, this lecture from Hellerstein's CS 186 is a good basis for understanding cache strategies. https://www.youtube.com/playlist?list=PLhMnuBfGeCDPtyC9kUf_h... In general, the entire course is probably worth watching. In the end, optimizing performance means looking at the specific properties of an app and engineering specific tradeoffs of time, space, and robustness. That's what the lecture illustrates.
