Sometimes it can be useful for clients to completely disable replies from the Redis server. For example when the client sends fire and forget commands or performs a mass loading of data, or in caching contexts where new data is streamed constantly. In such contexts to use server time and bandwidth in order to send back replies to clients, which are going to be ignored, is considered wasteful.

The CLIENT REPLY command controls whether the server will reply the client's commands. The following modes are available:

@return

When called with either OFF or SKIP subcommands, no reply is made. When called with ON:

@simple-string-reply: OK.
