So far with Lists and Sets we saw how to correlate a key with a value, or a group of values.
Hashes let us associate more than one value to a single key, and they are perfect to store object-like items.
For example, a person has a name and an age.
We can create a
HMSET person:1 name "Flavio" age 37
To get all the properties of a user, use
You can update a hash property using
HSET person:1 age 38
You can increment a value stored in a hash using
HINCRBY person:1 age 2
See all the hash commands here.
