Superseded by abstract-level. Split a levelup database into sublevels with their own keyspace, encoding and events.
subleveldown is a Node.js library for partitioning a levelup database into sublevels with independent keyspaces, encodings, and events. Built on top of levelup and encoding-down, it allows developers to create nested database sections—conceptually similar to SQL tables—where each sublevel maintains its own interface and can be configured with different key and value encodings. The project was authored by @mafintosh, inspired by level-sublevel by @dominictarr, and is now maintained as an official part of the Level ecosystem, though it has been superseded by abstract-level.
