Python Redis HSET Expire Time

If you are wondering about the HSET command in Redis, you have come to the right place.

The HSET command lets us set the value of a field within a hash stored at a key. Additionally, Redis lets us set an expiration time for keys, like hash fields, using the EXPIRE command.

The EXPIRE command lets us set expiration times for keys. This, including hash fields, ensures they automatically expire and are removed from the Redis database after a specified period.

How to Set Expiration Time for Hash Fields Using Python and Redis

• To begin with, set up a connection to the Redis server via a Redis client library in Python. The go-to choice for this purpose is redis-py.
• Then, we can use the HSET command to set the value of a field within a hash stored at a key. This command relies on three arguments: the key, the field name, and the value.

  # Set the hash field with an expiration time of 10 seconds
r.hset('my_hash', 'my_field', 'my_value')
• After setting the field value using HSET, we can use the EXPIRE command to set an expiration time for the key or specific hash fields. This command relies on two arguments: the key and the expiration time in seconds.

  # Set expiration time for the hash field
r.expire('my_hash:my_field', 10) # Expires in 10 seconds


Here is an example that demonstrates how to set a hash field value with an expiration time using Python and redis-py:


import redis
# Establish a connection to the Redis server
r = redis.Redis()
# Set the value of a field within a hash
r.hset('my_hash', 'field1', 'value1')
# Set an expiration time for the hash field
r.expire('my_hash:field1', 3600) # Expires in 1 hour (3600 seconds)


With Python and redis-py, we can set expiration times for hash fields in Redis easily. Let us know in the comments if you need further help.
