Method Details

maximumBackoff

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder maximumBackoff(long maximumBackoff)

The maximum backoff value (on average), in milliseconds. If set to a negative value, the algorithm will not be of the truncated variety.

Returns:

this.

multiplier

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder multiplier(double multiplier)

The multiplier on back-offs that is in the base of the exponent.

The default is 2, which results in doubling of average delays with additional failures. This generally should be set to a value greater than 1 so that delays tend to increase with more failures.

Returns:

this.

immediateFirst

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder immediateFirst(boolean immediateFirst)

Whether the first attempt after a failure should take place without delay.

To avoid a "stampeding herd" of reconnecting clients, jitter(boolean) can be enabled and initialJitterRange(long) can optionally be configured.

Returns:

this.

jitter

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder jitter(boolean jitter)

Whether (pseudo-)randomness should be applied when computing the exponential backoff.

Highly useful for avoiding the thundering herd problem.

Returns:

this.

initialJitterRange

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder initialJitterRange(long initialJitterRange)

The range of initial jitter amounts (in milliseconds) for when both ExponentialBackoffStrategy.isImmediateFirst() and ExponentialBackoffStrategy.isJitter() are true.

Returns:

this.

baseMillis

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder baseMillis(long baseMillis)

The milliseconds value for the first non-zero backoff. When ExponentialBackoffStrategy.isJitter() is true, this becomes an average targeted value rather than a strictly enforced constant.

Returns:

this.

maxRetries

public ExponentialBackoffStrategy.ExponentialBackoffStrategyBuilder maxRetries(int maxRetries)

The maximum number of retries that should be allowed.

A negative value corresponds to no limit. A zero value corresponds to no retries allowed. A positive value enforces a specific maximum.

Returns:

this.

build
