What are the five data type commands of redis

Redis supports five basic data type commands: string (SET/GET/INCR/DECR/APPEND/STRLEN) hash (HSET/HGET/HDEL/HLEN/HGETALL) list (LPUSH/RPUSH/LPOP /RPOP/LLEN/LRANGE) set (SADD/SMEMBERS/SREM/SCARD/SINTER/SUNION) ordered set (ZADD/ZSCORE/ZRANGE/ZRANK/ZCARD)

Five data type commands of Redis

Redis is an open source in-memory database that supports five basic data types: string, hash, list, set and ordered gather. The following are the commands for these five data types:

String

• SET: Set the value of the string
• GET: Get the character The value of the string
• INCR/DECR: Atomic increase/decrease the value of the string
• APPEND: Append content at the end of the string
• STRLEN: Get the length of the string

Hash

• HSET/HGET: Set/get the key-value pair in the hash
• HDEL: Delete the hash of key-value pairs
• HLEN: Get the number of key-value pairs in the hash
• HGETALL: Get all the key-value pairs in the hash

List

• LPUSH/RPUSH: Push elements at the head/tail of the list
• LPOP/RPOP: Pop elements from the head/tail of the list
• LLEN: Get the number of elements in the list
• LRANGE: Get the elements in the specified range in the list

Collection

• SADD: Add elements to the set
• SMEMBERS: Get all elements in the set
• SREM: Remove elements from the set
• SCARD: Get the number of elements in the set
• SINTER/SUNION: Find the intersection/union of sets

Ordered set

• ZADD: Add elements to in the ordered set, and specify its score
• ZSCORE: Get the score of the element in the ordered set
• ZRANGE: Get the element within the specified score range in the ordered set
• ZRANK : Get the ranking of elements in an ordered set
• ZCARD: Get the number of elements in an ordered set
