What are the methods for updating Redis data?

There are several ways to update Redis data:

1. SET command: Assigns the specified key with the specified value. If the key already exists, it will overwrite the existing value; if the key does not exist, it will create a new key and assign the value.
   Example: SET key value
2. MSET Command: Set multiple key-value pairs at the same time. You can set multiple key-value pairs at once, with each pair separated by a space.
   Example: MSET key1 value1 key2 value2 key3 value3.
3. HSET command: Set the value of a specified field in a hash table. If the hash table does not exist, create a new hash table and set the value; if the field already exists, overwrite the original value.
   Example: HSET key field value
4. HMSET command: sets the values of multiple fields in a hash table at the same time. It allows you to set multiple fields and values simultaneously, with spaces separating each field and its corresponding value.
   Example: HMSET key field1 value1 field2 value2 field3 value3
5. ZADD command: Adds one or more members to a sorted set, or updates the score of an existing member.
   Example: ZADD key score1 member1 score2 member2 score3 member3
6. SADD command: Add one or more members to a set.
   Example: SADD key member1 member2 member3
7. APPEND command: Appends a value to the end of the existing value of a specified key.
   Example: APPEND key value
8. INCRBY command: increase the value of a key by a specified increment.
   Example: INCRBY key increment

These are common methods for updating Redis data, choose the suitable method based on different data structures and requirements.
