getInitialRetryDelay()

public abstract Duration getInitialRetryDelay()

InitialRetryDelay controls the delay before the first retry/ poll. Subsequent retries and polls will use this value adjusted according to the RetryDelayMultiplier.

If there are no configurations, Retries have the default initial retry delay value of Duration.ZERO and LROs have a default initial poll delay value of Duration.ofMillis(5000) (5 seconds).

Returns
TypeDescription
org.threeten.bp.Duration

getInitialRpcTimeout()

public abstract Duration getInitialRpcTimeout()

InitialRpcTimeout controls the timeout for the initial RPC. Subsequent calls will use this value adjusted according to the RpcTimeoutMultiplier. RPC Timeout value of Duration.ZERO allows the RPC to continue indefinitely (until it hits a Connect Timeout or the connection has been terminated).

If there are no configurations, Retries have the default initial RPC timeout value of Duration.ZERO. LRO polling does not use the Initial RPC Timeout value.

Returns
TypeDescription
org.threeten.bp.Duration

getMaxAttempts()

public abstract int getMaxAttempts()

MaxAttempts defines the maximum number of retry attempts to perform. If this value is set to 0, the logic will instead use the totalTimeout value to determine retries. In the event that both the maxAttempts and totalTimeout values are both 0, the logic will not retry. If this value is greater than 0, and the number of attempts exceeds this limit, the logic will give up retrying even if the total retry time is still lower than totalTimeout.

If there are no configurations, Retries and LROs have the default max attempt value of 0. LRO polling does not use this value by default.

The first RPC invocation will be considered attempt #0. Subsequent calls (retries) will increment the number of attempts and the number of attempts will not exceed this value.

Returns
TypeDescription
int

getMaxRetryDelay()

public abstract Duration getMaxRetryDelay()

MaxRetryDelay puts a limit on the value of the retry delay, so that the RetryDelayMultiplier can't increase the retry delay higher than this amount.

If there are no configurations, Retries have the default max retry delay value of Duration.ZERO and LROs have a default max poll retry delay value of Duration.ofMillis(45000) (45 seconds).

Returns
TypeDescription
org.threeten.bp.Duration

getMaxRpcTimeout()

public abstract Duration getMaxRpcTimeout()

MaxRpcTimeout puts a limit on the value of the RPC timeout, so that the RpcTimeoutMultiplier can't increase the RPC timeout higher than this amount.

If there are no configurations, Retries have the default Max RPC Timeout value of Duration.ZERO. LRO polling does not use the Max RPC Timeout value.

Returns
TypeDescription
org.threeten.bp.Duration

getRetryDelayMultiplier()

public abstract double getRetryDelayMultiplier()

RetryDelayMultiplier controls the change in delay before the next retry or poll. The retry delay of the previous call is multiplied by the RetryDelayMultiplier to calculate the retry delay for the next call.

If there are no configurations, Retries have the default retry delay multiplier value of 1.0 and LROs have a default retry delay multiplier of 1.5.

Returns
TypeDescription
double

getRpcTimeoutMultiplier()

public abstract double getRpcTimeoutMultiplier()

RpcTimeoutMultiplier controls the change in RPC timeout. The timeout of the previous call is multiplied by the RpcTimeoutMultiplier to calculate the timeout for the next call.

If there are no configurations, Retries have the default RPC Timeout Multiplier value of 1.0. LRO polling does not use the RPC Timeout Multiplier value.

Returns
TypeDescription
double

getTotalTimeout()

public abstract Duration getTotalTimeout()

TotalTimeout has ultimate control over how long the logic should keep trying the remote call until it gives up completely. The higher the total timeout, the more retries and polls can be attempted. If this value is Duration.ZERO, then the logic will instead use the number of attempts to determine retries. In the event that both maxAttempts and totalTimeout values are both 0, the logic will not retry. If this value is non-Duration.ZERO, and the retry duration has reaches the timeout value, the logic will give up retrying even the number of attempts is lower than the maxAttempts value.

If there are no configurations, Retries have the default timeout value of Duration.ZERO and LROs have a default total timeout value of Duration.ofMillis(300000) (5 minutes).

Returns
TypeDescription
org.threeten.bp.Duration

isJittered()

public abstract boolean isJittered()

Jitter determines if the delay time should be randomized. In most cases, if jitter is set to true the actual delay time is calculated in the following way:

actualDelay = rand_between(0, min(maxRetryDelay, exponentialDelay))

The default value is true.

Returns

boolean

setInitialRetryDelay(Duration initialDelay)

public abstract RetrySettings.Builder setInitialRetryDelay(Duration initialDelay)

InitialRetryDelay controls the delay before the first retry/ poll. Subsequent retries and polls will use this value adjusted according to the RetryDelayMultiplier.

If there are no configurations, Retries have the default initial retry delay value of Duration.ZERO and LROs have a default initial poll delay value of Duration.ofMillis(5000) (5 seconds).

setInitialRpcTimeout(Duration initialTimeout)

public abstract RetrySettings.Builder setInitialRpcTimeout(Duration initialTimeout)

InitialRpcTimeout controls the timeout for the initial RPC. Subsequent calls will use this value adjusted according to the RpcTimeoutMultiplier. RPC Timeout value of Duration.ZERO allows the RPC to continue indefinitely (until it hits a Connect Timeout or the connection has been terminated).

If there are no configurations, Retries have the default initial RPC timeout value of Duration.ZERO. LRO polling does not use the Initial RPC Timeout value.

setJittered(boolean jittered) (deprecated)

public abstract RetrySettings.Builder setJittered(boolean jittered)

Deprecated. Retries always jitter.

Jitter determines if the delay time should be randomized. If jitter is set to true the actual delay time is calculated in the following way:

actualDelay = rand_between(0, min(maxRetryDelay, exponentialDelay))

The default value is true, and this method will be a no-op soon.

setLogicalTimeout(Duration timeout)

public RetrySettings.Builder setLogicalTimeout(Duration timeout)

Configures the timeout settings with the given timeout such that the logical call will take no longer than the given timeout and each RPC attempt will use only the time remaining in the logical call as a timeout.

Using this method in conjunction with individual RetrySettings timeout field setters is not advised, because only the order in which they are invoked determines which setter is respected.

Returns
TypeDescription

setMaxAttempts(int maxAttempts)

public abstract RetrySettings.Builder setMaxAttempts(int maxAttempts)

MaxAttempts defines the maximum number of retry attempts to perform. If this value is set to 0, the logic will instead use the totalTimeout value to determine retries. In the event that both the maxAttempts and totalTimeout values are both 0, the logic will not retry. If this value is greater than 0, and the number of attempts exceeds this limit, the logic will give up retrying even if the total retry time is still lower than totalTimeout.

If there are no configurations, Retries and LROs have the default max attempt value of 0. LRO polling does not use this value by default.

The first RPC invocation will be considered attempt #0. Subsequent calls (retries) will increment the number of attempts and the number of attempts will not exceed this value.
