PERSIST(3valkey)

✨ PERSIST(3valkey) ✨

okay bestie, so this is PERSIST, straight out of the Valkey Command Manual 💖 and honestly? it's giving "let her live forever" energy.

---

🌸 NAME 🌸

persist — Removes the expiration time of a key.

---

🎀 SYNOPSIS 🎀

PERSIST key

---

💅 DESCRIPTION 💅

so like, imagine your key has a timer on it. a little countdown, ticking away, about to go poof 💀. PERSIST is the girl who walks in and smashes the clock. ⏰✋

It removes the existing timeout on key, turning the key from volatile (a key with an expire set) into persistent (a key that will never expire as no timeout is associated). no cap. she's immortal now. 👑✨

---

🦋 REPLY 🦋

One of the following:

• valkey-protocol(7) Integer reply: 0 if key does not exist or does not have an associated timeout.
• valkey-protocol(7) Integer reply: 1 if the timeout has been removed.

⭐ COMPLEXITY ⭐

O(1) — literally instant, main character speed, no waiting around 🏃‍♀️💨

🔥 EXAMPLES 🔥

127.0.0.1:6379> SET mykey "Hello"
OK
127.0.0.1:6379> EXPIRE mykey 10
(integer) 1
127.0.0.1:6379> TTL mykey
(integer) 10
127.0.0.1:6379> PERSIST mykey
(integer) 1
127.0.0.1:6379> TTL mykey
(integer) -1

see how the TTL went from 10 to -1? that's the "no timeout, she's free" signal 💖
