org.infinispan.util.ExponentialBackOffImpl

All Implemented Interfaces:

ExponentialBackOff

public class ExponentialBackOffImpl
extends Object
implements ExponentialBackOff

The default ExponentialBackOff implementation for IRAC (asynchronous cross-site replication).

An exponential back-off implementation with min interval of 500 ms and a maximum of 300'000 ms (5 min). It uses a multiplier of 2 (each timeslot will be increase + 100% for each consecutive retry) and the final wait time is randomized, +- 50% of the timeslot.

12.0

Method Detail

backoffSleep

public void backoffSleep()
                  throws InterruptedException

Description copied from interface: ExponentialBackOff

It blocks the thread for a certain amount of time before retries the request.

The method is blocking and should be invoked when a request needs to be retried. It blocks the thread for a certain amount of time until it is allowed to do the request again.

Specified by:

backoffSleep in interface ExponentialBackOff

Throws:

InterruptedException - If the Thread is interrupted while blocked.

reset

public void reset()

Description copied from interface: ExponentialBackOff

Resets its state.

The blocking time in ExponentialBackOff.backoffSleep() increases with the number of consecutive retries. This methods resets its state back to the initial sleep time.
