Do I need Redis with MySQL?

When should I use Redis?
Redis can be used with streaming solutions such as Apache Kafka and Amazon Kinesis as an in-memory data store to ingest, process, and analyze real-time data with sub-millisecond latency. Redis is an ideal choice for real-time analytics use cases such as social media analytics, ad targeting, personalization, and IoT.
Can I use Redis with MySQL?
Redis is an open-source and in-memory data structure store that can be used for caching, real-time analytics, searching, and machine learning. Integrate Redis with PHP and MySQL will improve your application performance because Redis stores data in RAM. You can use it with databases like MySQL or MariaDB.
Is Redis faster than MySQL?

Primary memory is in lesser in size and much expensive than secondary so, Redis cannot store large files or binary data.
What are the disadvantages of Redis?
There is no query language (only commands) and no support for a relational algebra. You cannot submit ad-hoc queries (like you can using SQL on a RDBMS). All data accesses should be anticipated by the developer, and proper data access paths must be designed. A lot of flexibility is lost.
