CountBasedSlidingWindow

internal class CountBasedSlidingWindow(val capacity: Int, val minimumThroughput: Int) : FailureRateSlidingWindow<Boolean> (source)

A sliding window implementation that uses a count-based approach. To simplify the implementation, the window will only record boolean values, where true represents a successful operation and false represents a failed operation.

Parameters

capacity

the fixed size of the window.

minimumThroughput

the minimum number of calls that need to be recorded in the window for the failure rate to be calculated. Even if capacity is reached, the failure rate will not be calculated if the number of calls recorded in the window is less than this value.
