Why is Redis so fast? There are 3 main reasons as shown in the diagram below.
1. Redis is a RAM-based database. RAM access is at least 1000 times faster than random disk access.
2. Redis leverages IO multiplexing and single-threaded execution loop for execution efficiency.
3. Redis leverages several efficient lower-level data structures.
