Hi Adam,
We have a big load on the database and we want to implement a caching system in order to reduce the charge, you said that you dont use cache, but we want to know the different layers of cache and the usecases where caching makes the big difference, and what are the best ways to implement it. By the way we are thinking of hazelcast in Payara and Infinispan in Quarkus.
Thanks

By FrankTheTank from airhacks discord:

You often mention things you encountered, I would really be interested in, seeing your vast experience as a consultant, are project post-mortems and/or lessons learned.
As the saying goes, no plan survives the initial enemy contact and sometimes you just have to do ugly things.
Would love to hear more.
Kinda like the 'no one uses Java8, where in reality a lot of codebase has been written in Java8 and you often just update the version and add on top. Refactoring everything is just too expensive.

So, why not just skip the nesting functions and get straight to using a List function? After all, the Reference Function getting called repeatedly occupies Processing Time, and if you are doing that thousands to hundreds of thousands of times per second (as is common in games as recently as the Nintendo 64's Perfect Dark, and the PC's Minecraft), then you will be able to speed up your game by multiple FPS with such a basic optimization.

I love the explanation BTW.
