Field Detail

RETRIES_ATTEMPTED_CEILING

static final int RETRIES_ATTEMPTED_CEILING

Max permitted retry times. To prevent exponentialDelay from overflow, there must be 2 ^ retriesAttempted <= 2 ^ 31 - 1, which means retriesAttempted <= 30, so that is the ceil for retriesAttempted.

Method Detail

computeDelayBeforeNextRetry

Duration computeDelayBeforeNextRetry(RetryPolicyContext context)

calculateExponentialDelay

                                      Duration baseDelay,
