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.

Return Value

Integer reply, specifically:
• 1, if the timeout is set for the key.
• 0, if the key does not exist or timeout could not set.

Return Value

Integer
