redis 过期时间

EXPIRE | Docs https://redis.io/docs/latest/commands/expire/

The EXPIRE command supports a set of options:

• NX -- Set expiry only when the key has no expiry
• XX -- Set expiry only when the key has an existing expiry
• GT -- Set expiry only when the new expiry is greater than current one
• LT -- Set expiry only when the new expiry is less than current one

A non-volatile key is treated as an infinite TTL for the purpose of GT and LT. The GT, LT and NX options are mutually exclusive.
