+## Syntax
+
+    CLIENT PAUSE timeout [WRITE | ALL]
+
+**Time complexity:** O(1)
+**ACL categories:** @admin, @slow, @dangerous, @connection
+
+CLIENT PAUSE is a connections control command able to suspend all the Dragonfly clients for the specified amount of time (in milliseconds).
+
+The command performs the following actions:
+
+It stops processing all the pending commands from normal and pub/sub clients for the given mode. However interactions with replicas will continue normally. Note that clients are formally paused when they try to execute a command, so no work is taken on the server side for inactive clients.
+However it returns `OK` to the caller as soon as possible, so the `CLIENT PAUSE` command execution is not paused by itself.
+When the specified amount of time has elapsed, all the clients are unblocked: this will trigger the processing of all the commands accumulated in the query buffer of every client during the pause.
+Client pause currently supports two modes:
+
+* ALL: This is the default mode. All client commands are blocked.
+* WRITE: Clients are only blocked if they attempt to execute a write command.
+
+## Return
+Simple string reply: OK or an error if the timeout is invalid.
