✨ HKEYS — the valkey girlies' guide ✨

okay so bestie, we're in the Valkey Command Manual and today's main character is hkeys. it's giving "tell me everyone's names" energy 💅

🌸 NAME 🌸

hkeys — returns all fields in a hash. that's it. that's the whole job. iconic. 🎀

💖 SYNOPSIS 💖

HKEYS key

one argument. no chaos. we love a low-maintenance queen. ✨

🦋 DESCRIPTION 🦋

so basically: it returns all the field names in the hash that lives at key. not the values, bestie — just the names. it's the guest list, not the gifts. 🫶

📬 REPLY 📬

valkey-protocol(7) Array reply: a list of the fields in the hash. and if the key doesn't even exist? you get an empty list. no error, no drama, just vibes. 💜

🧠 COMPLEXITY 🧠

O(N) where N is the size of the hash. so like, the bigger the hash, the more it's gonna be walking around. still slay, just know what you're asking for. 🔥

👑 ACL CATEGORIES 👑

  • @hash
  • @read
  • @slow

three little tags and she's certified. periodt. 💅

📜 HISTORY 📜

  • Available since: 2.0.0 — an elder. a legend. been here since forever and still ate. 👑

🌈 EXAMPLES 🌈

ok watch this, it's so clean:

127.0.0.1:6379> HSET myhash field1 "Hello"
(integer) 1
127.0.0.1:6379> HSET myhash field2 "World"
(integer) 1
127.0.0.1:6379> HKEYS myhash
1) "field1"
2) "field2"

see?? we put two fields in, and HKEYS handed back exactly their names, numbered and everything. no notes. 💖
