Why are there stored procedures in tarantool\redis, if not in SQL, then in Lua?

Question

Database

In any case, this Lua is just "nailed" to the first one, and no one has ever even considered the possibility of applying something else there. (Or considered?)

Well, why didn't they consider several languages ​​for stored procedures at once, this can still be understood somehow. Kind of a monstrous complication. Ok, let 1 language.

But why did they stop at Lua. Why is it better than JavaScript, or at least Python? Few people know him, but there are many differences in him, even out of the blue you can run into something that is nowhere else at all. For example, ~=- it turns out to be simple !=. Mdaaa ... Even Pascal <>- and that is clearer.

Answer 1

Because the Lua interpreter is very small and lightweight, but it has a JIT compiler and high performance, and it is much easier to embed than any other language interpreter.
