With CLIENT NO-TOUCH ON, the commands this connection runs leave the keys’ last access time as it was. Use it for monitoring, auditing or backup tools that read many keys: without it, their reads make cold keys look recently used, which skews OBJECT IDLETIME and the choices of an LRU or LFU maxmemory-policy.

OFF restores normal behaviour. While it is on, the connection shows the T flag in CLIENT LIST.
