a database that keeps everything in memory because disks are for people with time to lose.
means an in-memory key-value store used as a cache, message broker, or database when speed matters more than storage size.
from built in 2009 by salvatore sanfilippo to speed up a startup's analytics; the name stands for remote dictionary server, which undersells how much it does now.
