When to use Redis Server?
Consider you have a MySQL database and you are constantly querying the database which reads the data from the secondary storage, computes the result, and returns the result.
If the data in the database is not changing much you can just store the results of the query in redis-server and then instead of querying the database which is going to take 100-1000 milliseconds, you can just check whether the result of the query is already available in redis or not and return it result which is going to be much faster as it is already available in the memory.
Note: In a messaging app, Redis can be used to store the last five messages that the user has sent and received using the built-list data structure provided in Redis.
Introduction to Redis
Redis is an in-memory data structure that is used for faster access to data. It is used to store data that needs to be accessed frequently and fast. It is not used for storing large amounts of data. If you want to store and retrieve large amounts of data you need to use a traditional database such as MongoDB or MYSQL. Redis provides a variety of data structures such as sets, strings, hashes, and lists.
- The Redis server is a program that runs and stores data in memory.
- You can just connect to that server and can use it to store and retrieve data faster.
- For that reason, Redis is not used for persistent storing of data as complete data will be lost if the system crashes.
- Redis is scalable as you can run multiple instances of the server.
- It is often used as a cache that stores data temporarily and provides faster access to frequently used data.
