Is it recommended to use caches on items that are queried a lot but only change on very little occasions? I've been on the search for something similar as XF1's simpleCache, but only found the CacheFactory so far and wasn't able to figure out how to use it (probably because it's 4am). So... is it still recommended to do manual caching in XF2 or is this done by the repository-system already? I've seen the word 'cached' in the dev-docs a few times, but mostly only when it says 'to get the uncached value'. If so, can someone point me in the right direction (e.g. where a cache is initialized/updated in the core files)?
