✨ MGET — the manual page, but make it make sense ✨

okay so bestie, welcome to the Valkey Command Manual 💅 this one's called MGET and it's lowkey one of the most iconic little commands in the whole repo. let's get into it 🫶

🌸 NAME 🌸

mget — atomically returns the string values of one or more keys.

like. it goes and grabs your stuff. all at once. atomically. no cap 💖

🎀 SYNOPSIS 🎀

MGET key [key...]

that's it. that's the whole vibe. one key, or a whole lil squad of keys, your call ✨

🦋 DESCRIPTION 🦋

Returns the values of all specified keys. 🫶

For every key that does not hold a string value or does not exist, the special value nil is returned. so if a key is missing or it's holding something that isn't a string, you don't get an error, you just get nil in that slot. it's giving "no thoughts, head empty, but polite about it" 💀

and because of that whole nil situation, the operation never fails. literally never. it cannot fail. main character energy fr fr 👑

💖 REPLY 💖

valkey-protocol(7) Array reply: a list of values at the specified keys.

so you get an array back, one entry per key you asked about, in the exact order you asked. periodt. ✨

⭐ COMPLEXITY ⭐

O(N) where N is the number of keys to retrieve.

so like, the more keys you throw at it, the more work it does. obviously. it's proportional, bestie, that's the whole thing 🌈

👑 HISTORY 👑

  • Available since: 1.0.0

she's been here since the beginning. an OG. a legend. we stan 🎀

🌸 EXAMPLES 🌸

okay so here's the classic lil demo, look how cute this is:

127.0.0.1:6379> SET key1 "Hello"
OK
127.0.0.1:6379> SET key2 "World"
OK
127.0.0.1:6379> MGET key1 key2 nonexisting
1) "Hello"
2) "World"
3) (nil)

see how nonexisting just quietly returns (nil) instead of making a whole scene? that's the energy. no drama, no error, just vibes 💜
