Virtual Memory in Redis

Virtual memory in Redis allows the database to store and manage data larger than the available physical RAM. It swaps less frequently accessed data to disk, freeing up RAM, but this can slow down access times since disk read is slower than RAM. Consider performance trade-offs and alternatives for large datasets.

How does Redis store data?

Redis is an in-memory data store. It stores data primarily in RAM, allowing extremely fast read and write operations. The data is organized using key-value pairs, where keys are unique identifiers, and values can be of different types, including strings, lists, sets, sorted sets, hashes, bitmaps, and more. Data in Redis is accessed by keys, making it a highly efficient and simple data store.
