Simplicity: Redis has a simple, text-based protocol and well-documented command set Ubiquity: Redis is battle tested in production workloads at a massive scale. There is a good chance you indirectly interact with Redis several times daily Versatility: Redis is the de facto standard for use cases...
NAND has a limited ROM memory space, meaning the program won't compile if there's too much code. In fact, the final version of this program uses 99.2% of the instruction memory space. NAND has a limited RAM memory space, meaning the program has to be careful to optimize heap memory us...
