yarts

yet another real time statistics

Building

mvn clean install

Running

java --enable-preview -jar target/yarts.jar

Assumptions

App is collecting stats in 1 second buckets, cleaning each bucket when it is older than 1 min. Such implementation does not give stats from exactly 60 seconds but rather from last full 60 seconds Also statistics for each instrument are collected separately, so there is minimal chance that on the edge of last full second tick will be collected globally but not in local instruments stats

Original implementation was using WebFlux, but unfortunately required JavaMelody does not support it and crash, so finally app is running on classic WebMvc.

Possible improvements

In real live app I would definitely improve tests, a lot more tests with mocks + probably some performance tests Also real live app will require some kind of scheduler to clean up TimeFrame for long not seen instruments to free up some memory.
