SummaryStore

SummaryStore is an approximate time–series store, designed for analytics, capable of storing large volumes of time-series data (∼1 petabyte) on a single node; it preserves high degrees of query accuracy and enables near real-time querying at unprecedented cost savings. SummaryStore contributes time-decayed summaries, a novel abstraction for summarizing data streams, and returns reliable error estimates alongside the approximate answers, supporting a range of machine learning and analytical workloads.
