Redis can do TTL without TTL

Everyone knows about EXPIRE for keys.

But Redis can also remove elements from a ZSET, SET, or LIST using TTL-like logic — by storing them with a timestamp as the score and cleaning them up manually.

You don’t need cron for this. Just:

ZADD my:queue 1715366400 "job:123"

Then periodically:

ZREMRANGEBYSCORE my:queue -inf <current_time>

No real TTL. Just time that’s passed.
