    String type is the most basic data type in Redis, it can store any form of string, including binary data. It can be used to store a user's mailbox, JSONized objects, or even an image. The maximum size of data a string type key can store is 512MB. String types are the basis for the other four data types, and the difference between the other data types and string types is, in some ways, simply the way strings are organized. For example, list types organize strings as lists, while collection types organize strings as collections.
