1 week ago Lalit Bhagtani 0
In this tutorial, we will learn about how to remove expiration time ( timeout ) of a key stored in redis datastore, by using a COMMAND – PERSIST in redis-cli. When we set an expiration time on a key using EXPIRE/PEXPIRE or EXPIREAT/PEXPIREAT, its state becomes Volatile ( a key with an expiration time set ). PERSIST command change its state to Persist state by removing expiration time associated with it. The syntax of redis PERSIST command is as follows :-
redis host:post> PERSIST <key name>
- 1 if the timeout of key was removed. - 0 if key does not exist or does not have a timeout.
