2024-05-21Fixed #35405 -- Converted get_cache_name into a cached property in ↵Adam Johnson

This work migrates get_cache_name() to be a cached property to optimize performance by reducing unnecessary function calls when working with related fields, given that its value remains constant.

2021-11-03Fixed #32996 -- Cached PathInfos on relations.Keryn Knight
PathInfo values are ostensibly static over the lifetime of the object for which they're requested, so the data can be memoized, quickly amortising the cost over the process' duration.
