When to use Redis , advantages of Redis and best practices of Redis .Example of Redis With Node JS.

Redis is used as data storage in software engineering , Redis storage is faster than any database storage , because Redis store data In memory and this storage is working as cache storage . But Redis storage is not persistence , once system shutdown all memory will be gone . Now most be thinking than how it is good .It is great if we use Redis with Node JS,

mysql, Mongodb

Solution for persistency :We need to create a mysql table or mongodb collection in our database which holds all cache data inside that table or collection , so if system goes down we have all cache details, once system will be up our script or application will again sync whole cache from that table to redis server.
