BITOP is a good complement to the pattern documented in the BITCOUNT command documentation. Different bitmaps can be combined in order to obtain a target bitmap where the population counting operation is performed. See the article called "Fast easy realtime metrics using Redis bitmaps" for an interesting use cases.
