This article is about what the redis data types are. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

There are five types of redis data:

string string (can be integer, float, and string, collectively called element)

list (implement queue, elements are not unique, first-in first-out principle)

set (different elements)

hash value (hash key must be unique)

sort set

2. Common commands of string type:

Add: incr

Self-reduction: decr

Add: incrby

Less: Decrby

Common commands supported by list type:

lpush: Push from the left

lpop: pop up from the right

push: push from right

rpop: pop up from the right

llen: View the length of a list data type

4. Common commands supported by set type:

sadd: add data

scard: View the number of elements present in the set data

sismember: Determine whether an element exists in the set data

srem: Delete elements from a set of data

5. Common commands supported by hash data type:

hset: Add hash data

hget: Get hash data

hmget: Get multiple hash data

6, sort set and hash is very similar, but also the form of mapping storage:

zadd: add

zcard: query

zrange: Sort data
