Redis PEXPIRE
Redis PEXPIRE Command
The Redis Pexpire command is used to set the time of living of a key in milliseconds instead of seconds. After the expiry time, key will not be available in redis.
Here are some common uses and scenarios for the "PEXPIRE" command:
- Fine-grained TTL: Set precise expiration times for keys in milliseconds.
- Micro-caching: Cache data for very short durations with millisecond precision.
- Rate Limiting: Control access rates with precise time windows.
- Temporary Data: Manage short-lived tokens or temporary state with accuracy.
Syntax:
PEXPIRE KEY_NAME TIME_IN_MILLISECONDS
Available since
2.6.0.
