What should you not use Redis for?
No password.
What is the use case for 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.
How reliable is Redis?
Redis is actually a very reliable engine to store data, as long as you keep in mind its design principles. (the Aphyr post is great with that). The replication and cluster modes can add additional complexity (but of course mysql master-slave or master-master have their own risks and complexity as well.)
Why is Redis expensive?
Yes, It is expensive. Redis is mostly used to implement cache which are supposed to be faster than the primary data-store. As it is used as cache, we can have this trade off of price vs speed.
Why Redis is so popular?
Redis is a data structure server. As a key-value data store, Redis is similar to Memcached, although it has two major advantages over that option: support of additional datatypes and persistence. All of the data is stored in RAM, so the speed of this system is phenomenal, often performing even better than Memcached.
Which are not the disadvantages of Redis?
With Redis, you cannot. Redis is a data structure server. 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).
What is Redis good for?
Redis also provides in-built support for replication, transactions and excellent support for data persistence. Redis is a good choice primarily if your application needs to store and retrieve a huge amount of data.
Is Redis free to use?
Yes, Redis is free to use. There is a community version of Redis that is very suitable for many use cases.
How is Redis used?
Redis is often used for cache management and speeding up web applications. Redis is written in ANSI C and runs on POSIX systems such as Linux, Mac OS X and Solaris. It can be accessed by applications through its client API library.
What is Azure cache for Redis?
Azure Cache for Redis is based on the popular software Redis. It is typically used as a cache to improve the performance and scalability of systems that rely heavily on backend data-stores. Performance is improved by temporarily copying frequently accessed data to fast storage located close to the application.
