FLUSHALL deletes every key in every database and all tags. It also deletes the entries held by HotKV’s AI features, such as prompt and semantic cache entries, so the server is left empty. Configuration-like data shared by the cluster, such as model prices and tenants, is kept. Like any write, it is sent to replicas and written to the append-only file. There is no undo.

In HotKV Cloud, the CLI tab of the panel does not run FLUSHALL. Send it from your own client connection.

Compatibility

Section titled “Compatibility”

Same as Redis 7 and Valkey 8, except that ASYNC does not defer freeing memory to the background. Clearing the AI feature data matches what FLUSHALL does to module data in Redis.
