Answer by Thomas John for How to "EXPIRE" the "HSET" child key in redis?

You can expire Redis hashes in ease, Eg using python

import redis
conn = redis.Redis('localhost')
conn.hmset("hashed_user", {'name': 'robert', 'age': 32})
conn.expire("hashed_user", 10)

This will expire all child keys in hash hashed_user after 10 seconds

same from redis-cli,

127.0.0.1:6379> HMSET testt username wlc password P1pp0 age 34
OK
127.0.0.1:6379> hgetall testt
1) "username"
2) "wlc"
3) "password"
4) "P1pp0"
5) "age"
6) "34"
127.0.0.1:6379> expire testt 10
(integer) 1
127.0.0.1:6379> hgetall testt
1) "username"
2) "wlc"
3) "password"
4) "P1pp0"
5) "age"
6) "34"

after 10 seconds

127.0.0.1:6379> hgetall testt
(empty list or set)
