TTL for Redis keys

Question

NoSQL

Can you please tell me what is the default TTL for keys in Redis and what parameter in redis.conf is responsible for it? Thank you.

Answer 1

By default, ttl is not set - it lives “forever”, for more details - the expire command

Answer 2

Thank you. Further it is clear.

Answer 3

So. I’ll immediately ask the second question ... I can’t understand (please don’t hit hard - the first acquaintance with Redis - there is little information in my head yet)
In what cases will the keys be deleted on their own - if I don’t specify TTL for them using the Expire command ?

Answer 4

Guys, thank you all. Especially aber . Figured out what the problem was. I saved the key with the name keys - apparently you can’t do this, because there is a KEYS command (I corrected it for keys_redis - everything I do seems to work).
