command info xread 1) 1) "xread" 2) (integer) -4 3) 1) readonly 2) movablekeys 4) (integer) 1 5) (integer) 1 6) (integer) 1 7) 1) @read 2) @stream 3) @slow 4) @blocking Here 4) (integer) 1 is the position ( 1 ) of the key argument. So it uses args[1] which is count . So everything works as expected (but incorrectly).
There is movablekeys in command flags.It is the note from https://redis.io/commands/command.
movablekeys - keys have no pre-determined position. You must discover keys yourself. So the client should do more to discover keys, right?
