Command Reference

The full low-level reference for Lux. Use this page when you want raw command access across cache, tables, vectors, queues, realtime, and time series.

If you are building an application on Lux Cloud, most teams start with Tables, the SDK, and Realtime. Drop down to raw commands when you want direct control or full Redis client compatibility.
