There is still the misconception that if you just want to cache, you don't need data types. One of the biggest Redis use cases, Twitter (I didn't check if they still use it in the last two years, I guess so, and anyway used it for many years), beg to differ. But in general almost all the serious caching scenarios using Redis represent part of the stored data, in memory, with an organization that allows updating the cache and selectively retrieving from the cache like if it was the primary (oh, not just the primary, specified queries you could do against the primary), so everything is incremental and there is no need to cache multiple "views" of the same thing.
