PSETEX(3valkey)

💖 PSETEX 💖

okay bestie, welcome to psetex — it's from the Valkey Command Manual and it's literally the moment your key gets a value and a lil countdown, in milliseconds. slay.

---

✨ NAME ✨

psetex — sets both the string value and the expiration time in milliseconds of a key. the key gets created if it doesn't exist yet. no cap. 🎀

---

🌸 SYNOPSIS 🌸

PSETEX key milliseconds value

---

🦋 DESCRIPTION 🦋

so here's the tea: PSETEX works exactly like SETEX with one (1) single difference — the expire time is given in milliseconds instead of seconds. that's it. that's the whole glow-up. ⏱️

💅 Alternative

you could also just use SET with the PX argument. same vibe, different font. 🫶

🍓 EXAMPLES 🍓

watch her work:

127.0.0.1:6379> PSETEX mykey 1000 "Hello"
OK
127.0.0.1:6379> PTTL mykey
(integer) 990
127.0.0.1:6379> GET mykey
"Hello"

like… 1000 ms later and PTTL is already down to 990?? the way time just moves. 😭🕰️
