Class ExponentialBackoffRetry

java.lang.Object

alluxio.retry.SleepingRetry

alluxio.retry.ExponentialBackoffRetry

All Implemented Interfaces:

RetryPolicy

@NotThreadSafe
public class ExponentialBackoffRetry
extends SleepingRetry

Each retry will cause a sleep to happen. This sleep will grow over time exponentially so each sleep gets much larger than the last. To make sure that this growth does not grow out of control, a max sleep is used as a bounding.

Constructor Detail

ExponentialBackoffRetry

public ExponentialBackoffRetry(int baseSleepTimeMs,
                               int maxSleepMs,
                               int maxRetries)

Constructs a new retry facility which sleeps for an exponentially increasing amount of time between retries.

Parameters:

baseSleepTimeMs - the sleep in milliseconds to begin with

maxSleepMs - the max sleep in milliseconds as a bounding

maxRetries - the max count of retries

Method Detail

getSleepTime

protected long getSleepTime()

Description copied from class: SleepingRetry

How long to sleep before the next retry is performed. This method is used with SleepingRetry.getSleepUnit(), so all time given here must match the unit provided.
