How many data types are there in redis
This article will explain in detail how many data types there are in redis. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.
1. 5 data types of 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
