Command reference

HotKV implements 294 core commands across 25 categories, matching the Redis command set plus a handful of HotKV-exclusive additions. None of the core commands require a license or a specific plan. The Enterprise edition adds commands for AI and LLM workloads, rate limiting, time series, the feature store, audit, encryption, replication, multi-tenancy, observability, and licensing. Every command has its own page with syntax, options, RESP2 and RESP3 replies, examples, and notes on how it compares with Redis and Valkey; the full list is below.

HotKV-exclusive features

Features and command families that do not exist in Redis or Valkey, available on every plan with no license required:

Feature	Commands	Description
Nanosecond TTL	NEXPIRE, NTTL, NEXPIREAT	Set and read key TTLs in nanoseconds
Key Tagging	TAG.SET/GET/REM/MEMBERS/INTER/COUNT/EXISTS	Attach labels to keys and find keys by label

Plans and licenses

The enterprise commands, all except LICENSE.*, need a license feature: on HotKV Cloud it comes with the plan, and On-Premise it comes with your license. On HotKV Cloud:

• Performance and Scale include the AI and LLM commands, rate limiting, time series, the feature store, vector snapshots, and observability and alerting.
• Scale adds the audit log, encryption at rest, replication, and multi-tenancy.
• Starter includes none of them.

An unlicensed command replies -NOLICENSE <feature> requires a HotKV license. Contact sales@hotkv.com. Check what your server has with LICENSE.INFO. Each command page shows what it needs under HotKV Cloud and On-Premise.
