def write_request(arguments)

The redis server doesn't want actual objects (e.g. integers) but only bulk strings. So, we inline it for performance.

def write_request(arguments)
	write_lines("*#{arguments.size}")
	
	@count += 1
	
	arguments.each do |argument|
		string = argument.to_s
		
		write_lines("$#{string.bytesize}", string)
	end
end

def write_lines(*arguments)

In the case of Redis, we do not want to perform a flush in every line, because each Redis command contains several lines. Flushing once per command is more efficient because it avoids unnecessary writes to the socket.

def write_lines(*arguments)
	if arguments.empty?
		@stream.write(CRLF)
	else
		arguments.each do |arg|
			@stream.write(arg)
			@stream.write(CRLF)
		end
	end
end
