org.apache.pinot.spi.utils.retry.ExponentialBackoffRetryPolicy

All Implemented Interfaces:

RetryPolicy

public class ExponentialBackoffRetryPolicy
extends BaseRetryPolicy

Retry policy with exponential backoff delay between attempts.

The delay between the i^th and (i + 1)^th attempts is between delayScaleFactorⁱ * initialDelayMs and delayScaleFactor^{(i + 1)} * initialDelayMs.
