PING [message]

Returns PONG if no argument is provided, otherwise return a copy of the argument as a bulk. This command is useful for: 1. Testing whether a connection is still alive. 1. Verifying the server’s ability to serve data - an error is returned when this isn’t the case (e.g., during load from persistence or accessing a stale replica). 1. Measuring latency.

If the client is in RESP2 and is subscribed to a channel or a pattern, it will instead return a multi-bulk with a “pong” in the first position and an empty bulk in the second position, unless an argument is provided in which case it returns a copy of the argument.

Any of the following:

• valkey-protocol(7) Simple string reply: PONG when no argument is provided.
• valkey-protocol(7) Bulk string reply: the provided argument.
