Why does Redis use integer database numbers instead of strings? It seems like it would be trivial to keep a small internal data structure which maps strings to the “actual” integer.

the reason why Redis does not use strings as DB names but indexes is that the goal and ability of Redis databases is not to provide an outer level of dictionary: Redis dictionaries can’t scale to many dictionaries, but just to a small number (it is a tradeoff), nor we want to provide nested data structures per design, so this are just “a few namespaces” and as a result using a numerical small index seemed like the best option.
