Redis supports data structure types

Support multiple types of data structures
1、 Binary safe string
2、Lists: A collection of string elements sorted by insertion order . They are basically linked lists （linked lists）.
3、Sets: A collection of unrepeated and unordered string elements .
4、Sorted sets, similar Sets, But each string element is associated with a string element called score Floating values （floating number value）. The elements in it always pass through score Sort it out , So the difference is , It's a series of elements that can be retrieved .（ For example, you might ask ： Give me the front 10 One or the back 10 Elements ）.
5、Hashes, from field Associated with value Composed of map.field and value It's all strings . This sum Ruby、Python Of hashes It's like .
6、Bit arrays ( Or say simply bitmaps): By special orders , You can take String Value as a series of bits Handle ： You can set and clear individual bits, Count all of them set to 1 Of bits The number of , The first one found is set to 1 or 0 Of bit, wait .
7、HyperLogLogs: This is used to estimate a set The number of elements in the probability of the data structure .
