Memory Mapped Files DB

[solarsystemic]

Note that Rust's www.meilisearch.com uses Lightning Database uses memory mapped files. Rust: with Sled and JammDB - MMF's as well.

I tried APL and J memory mapped files - fast and easy. Create empty small to huge arrays then store and pick any index - one by one. Very similar - perhaps to https://www.symas.com/lmdb which is tiny and faster than sqlite. Lightning is also ACID. https://en.wikipedia.org/wiki/Lightning_Memory-Mapped_Database One or more Rust wrappers - https://docs.rs/heed/latest/heed/ Safe persistence and speed and ease -great game DB?
