Persisting data with Redis

Redis is an open source in-memory key-value data store. Used in the correct setting, Redis can be a fast-performing data store. It is often used to provide caching in applications but can also be used as a database.

Redis, an acronym for Remote Dictionary Server, is an in-memory data structure store, often used as a database, cache, and message broker. It excels in scenarios requiring high speed and efficiency, such as caching, session management, real-time analytics, and message queuing. Redis’s ability to support various data structures, combined with its atomic operations and publish/subscribe (pub/sub) messaging capabilities, makes it a powerful tool for enhancing the performance and scalability of Node.js applications. Its in-memory nature ensures rapid access to data, significantly reducing latency compared to traditional disk-based databases, making it ideal for applications where speed is critical.

In the context of Node.js, Redis is...
