RetryPolicy

public RetryPolicy(RetryPolicy.RetryCondition retryCondition,
                   RetryPolicy.BackoffStrategy backoffStrategy,
                   int maxErrorRetry,
                   boolean honorMaxErrorRetryInClientConfig)

Constructs a new retry policy. See PredefinedRetryPolicies for some pre-defined policy components, and also the default policies used by SDK.

Parameters:

retryCondition - Retry condition on whether a specific request and exception should be retried. If null value is specified, the SDK' default retry condition is used.

backoffStrategy - Back-off strategy for controlling how long the next retry should wait. If null value is specified, the SDK' default exponential back-off strategy is used.

maxErrorRetry - Maximum number of retry attempts for failed requests.

honorMaxErrorRetryInClientConfig - Whether this retry policy should honor the max error retry set by ClientConfiguration.setMaxErrorRetry(int)
