InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
But some caching algorithms could be better than others on real-world data.
Would you want me to run something like https://github.com/twitter/cache-trace on both Redis/(LRU,LFU) and Dragonfly and see which one has higher hit-rate for the same memory requirements? Would this be a good test to decide if Dragonfly improves on Redis caching quality?
It is handled by W-TinyLFU where I use this scenario as a stress test [1]. While LIRS / LIRS2 did not pass this one scenario, the quality of the work behind that policy leads me to believe it could be improved to handle that case.
