Realtime metrics using Redis bitmaps
It is very good to see this article and Redis bitmaps exploited, since it is an extremely memory efficient way to store data, and given the encoding, it is extremely fast to also fetch big amount of information this way.I really suggest to also looking at GETRANGE and SETRANGE operations that allow to access sub-ranges of a large bitmap fetching or setting arbitrary ranges fo bits.Probably Lua scripting in 2.6 will enable a lot more interesting things combining server side execution and bitmaps. Thanks for sharing this work.
