What is advantage of Redis Data Structured Server

Topic : 

Redis data structured server  and sample code , use cases . 

Following essential points , why do we need Redis 

-- Ease of store  and cache key - value pairs 

-- Inbuilt use of  in memory (i.e)  Redis use  memory mapped techniques

-- The key - value cached  values never get lost , as Redis used MMAP concepts 

-- REDIS runs over TCP, UDP , UNIX Domain socket 

-- You can configure Redis either in your local host , or in remote server 

-- Hence Redis shall be called as  Centralized Remote Data Structured Server 

--   Redis has different data types , and has DATABASE similar to other SQL servers 

-- you can create your own data base and have key value mapping stores per data base ... 

--- The data base can be switched to other 

-- Very simple way of doing  SET, GET method to read and write 'key - value ' into redis database server 

-- You can configure redis configuration file , for optimized memory and data base configurations 

Applications  use case of interest 

--- To Maintain centralized unique key value pair

--- Dynamic way of generating unique key and store  value (as input from user) 

Example: 

 You have some data to be stored uniquely across your networks. 

Redis can create you unique key, you shall store your data with that unique key . 

Typically  Redis shall be applied on  User Sessions Accounting,  File Management,  Choosing File with suffix as key, 

Web Caching Contents (file naming as unique key).
