RESP3 Null values

[einar-hjortdal]

I am writing a KeyDB client library for the V language, I have noticed that KeyDB is currently responding with RESP2 $-1\r\n and *-1\r\n instead of using RESP3 _\r\n.

Is KeyDB going to switch to RESP3 protocol or is it going to stay on RESP2?

Each connection needs to manually let the server know it speaks RESP 3 by sending:
HELLO 3
The default behaviour is to use RESP 2

The HELLO command seems to be missing form the docs. Am I wrong?

Correct HELLO is missing from the docs
