Class StatBucket

java.lang.Object
io.nosqlbench.nb.api.stats.StatBucket
public final class StatBucket extends Object
This is a relatively efficient statistics bucket which can maintain moving aggregates over a window of samples for count, mean, variance, stddev, sum. This is particularly useful when you know that each update to the data will likely be used in a query.
