Counters, Percentiles, etc for in-memory metrics capture.
This is a utility library that started by extracting code from Hystrix for use in other projects that don't need Hystrix.
For example:
- RollingNumber: a rolling number which can be used to track counters (increment) or set values over time
- RollingPercentile: a rolling window for percentile calculations such as median, 90th, 99th, etc
