@Internal
public final class AIMDRateLimitingStrategy
extends Object

Additive Increase/Multiplicative Decrease implementation of throttling Strategy This implementation is not thread safe.

This Strategy is used by the writer to implement rate limiting on request thoroughput to match throttled destinations.

AIMDRateLimitingStrategy

public AIMDRateLimitingStrategy(int increaseRate,
                                double decreaseFactor,
                                int rateThreshold,
                                int initialRate)

参数:

increaseRate - Linear increase value of rate limit on each acknowledgement.

decreaseFactor - Exponential decrease factor of rate limit on each failure.

rateThreshold - Threshold for maximum value of rate limit, this can be enforced due to writer or destination specific limits.

initialRate - Initial rate limit to start with.
