Redis data type Induction

 

Redis data types are all key-value pairs. The data type should be the value data type, such as string, set, list, etc., are the data set format of the value corresponding to the key value.
The difference between different data types is that the value storage format is different.

On the whole, the redis slave data type is relatively simple. 2. All operations are performed in the memory. The single thread of the slave node avoids the lock mechanism, which improves redis performance.

Key Value related operations

1. dbsize is the number of key values, which is irrelevant to the data type and the content in the value (SET ).

You can use keys or scan to query key values. scan can be considered as a keys with pagination.
