Class RetryPolicyProperties

java.lang.Object

dev.restate.sdk.springboot.RetryPolicyProperties

public class RetryPolicyProperties
extends Object

Configuration properties for Restate's retry policy when retrying failed handler invocations.

This policy controls an exponential backoff with optional capping and a terminal action:

• initialInterval: delay before the first retry attempt.
• exponentiationFactor: multiplier applied to the previous delay to compute the next delay.
• maxInterval: upper bound for any computed delay.
• maxAttempts: maximum number of attempts (initial call counts as the first attempt).
• onMaxAttempts: what to do when maxAttempts is reached.

Unset fields inherit the corresponding defaults from the Restate server configuration.

Method Details

getInitialInterval

public @Nullable Duration getInitialInterval()

Initial delay before the first retry attempt.

If unset, the server default is used.

setInitialInterval

public void setInitialInterval(@Nullable Duration initialInterval)

Initial delay before the first retry attempt.

If unset, the server default is used.

getExponentiationFactor

public @Nullable Double getExponentiationFactor()

Exponential backoff multiplier used to compute the next retry delay.

For attempt n, the next delay is roughly previousDelay * exponentiationFactor, capped by getMaxInterval() if set.

setExponentiationFactor

public void setExponentiationFactor(@Nullable Double exponentiationFactor)

Exponential backoff multiplier used to compute the next retry delay.

For attempt n, the next delay is roughly previousDelay * exponentiationFactor, capped by getMaxInterval() if set.

getMaxInterval

public @Nullable Duration getMaxInterval()

Upper bound for the computed retry delay.

If set, any computed delay will not exceed this value.

setMaxInterval

public void setMaxInterval(@Nullable Duration maxInterval)

Upper bound for the computed retry delay.

If set, any computed delay will not exceed this value.

getMaxAttempts

public @Nullable Integer getMaxAttempts()

Maximum number of attempts before giving up retrying.

The initial call counts as the first attempt; retries increment the count by 1. When giving up, the behavior defined with getOnMaxAttempts() will be applied.

See Also:

• RetryPolicyProperties.OnMaxAttempts

setMaxAttempts

public void setMaxAttempts(@Nullable Integer maxAttempts)

Maximum number of attempts before giving up retrying.

The initial call counts as the first attempt; retries increment the count by 1. When giving up, the behavior defined with getOnMaxAttempts() will be applied.

See Also:

• RetryPolicyProperties.OnMaxAttempts

getOnMaxAttempts

public @Nullable RetryPolicyProperties.OnMaxAttempts getOnMaxAttempts()

Behavior when the configured getMaxAttempts() is reached.

See Also:

• RetryPolicyProperties.OnMaxAttempts

setOnMaxAttempts

public void setOnMaxAttempts(@Nullable RetryPolicyProperties.OnMaxAttempts onMaxAttempts)

Behavior when the configured getMaxAttempts() is reached.
