Interface RetryPolicy

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface RetryPolicy

A policy for retry execution.

Method Summary

Modifier and Type	Method and Description
static RetryPolicy	constantDelay(long delay) Create a constant delay retry policy.
long	delay(Throwable failure, int retryCount) Compute a delay in milliseconds before retry is executed.
static RetryPolicy	exponentialDelayWithJitter(long initialDelay, long maxDelay) Create an exponential delay with jitter retry policy.
static RetryPolicy	linearDelay(long initialDelay, long maxDelay) Create a linear delay retry policy.

Method Detail

constantDelay

static RetryPolicy constantDelay(long delay)

Create a constant delay retry policy.

Parameters:

delay - the constant delay in milliseconds

linearDelay

static RetryPolicy linearDelay(long initialDelay,
                               long maxDelay)

Create a linear delay retry policy.

Parameters:

initialDelay - the initial delay in milliseconds

maxDelay - maximum delay in milliseconds

exponentialDelayWithJitter

static RetryPolicy exponentialDelayWithJitter(long initialDelay,
                                              long maxDelay)

Create an exponential delay with jitter retry policy.

Based on Full Jitter in Exponential Backoff And Jitter.

Parameters:

initialDelay - the initial delay in milliseconds

maxDelay - maximum delay in milliseconds

delay

long delay(Throwable failure,
           int retryCount)

Compute a delay in milliseconds before retry is executed.

Parameters:

failure - the failure passed to the operation Promise

retryCount - the number of times operation has been retried already

Returns:

a delay in milliseconds before retry is executed
