@iko1 if it's ok with you, I am asking you to review.

@b0bleet, do you need this command because you use Dragonfly, or you just wanted to contribute? Can you please add yourself to CONTRIBUTORS.md ?

Hi @romange, Thanks for your reply. Actually, I want to contribute to DragonFly because I'm very interested in in-memory database development. At the moment I do analyze internal structure of DragonFly to contribute core components.
