This a simpler / cleaner version of fbcode's ServiceData for hphp. Currently we support only flat counters, MultiLevelTimeSeries and Histograms. We can add more stats types later on as needed. ServiceData is a global entry point for all this stuff. The current idea is to completely decouple data input and export. ServiceData internally has three separate maps tracking flat counters, timeseries and histograms. These maps are wrapped by spin locks and protected by folly::Synchronized. ServiceData provides three functions to create/retrive counter objects. The counter objects are thread safe (protected again by spin locks and folly::Synchronized).
