This article is to share with you about the data types in Redis. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

5 data types of 1.redis:

String string (can be integer, floating-point, and string, collectively referred to as elements)

List list (implementation queue, non-unique elements, first-in, first-out principle)

Set collection (different elements)

Hash value (key for hash must be unique)

Sort set ordered set

Common commands of the 2.string type:

Self-added: incr

Self-subtracting: decr

Add: incrby

Minus: decrby

Common commands supported by the 3.list type:

Lpush: push in from the left

Lpop: pop up from the right

Rpush: push from the right

Rpop: pop up from the right

Llen: view the length of a list data type

Common commands supported by the 4.set type:

Sadd: adding data

Scard: view the number of elements that exist in set data

Sismember: determines whether an element exists in set data

Srem: delete an element from an set data

Common commands supported by the 5.hash data type:

Hset: adding hash data

Hget: getting hash data

Hmget: get multiple hash data

6.sort set is very similar to hash and is also storage in the form of mapping:

Zadd: addin

Zcard: query

Zrange: data sorting

These are the data types in Redis, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
