Method Details

executeWithRetry

public static <T> T executeWithRetry(Callable<T> operation,
 int maxRetries,
 Duration initialDelay)
                              throws Exception

Retries an operation with exponential backoff. Uses default retry predicate (retries on any exception) and default operation name.

Type Parameters:

T - Return type of the operation

Parameters:

operation - The operation to retry

maxRetries - Maximum number of retry attempts

initialDelay - Initial delay duration

Returns:

The result of the operation

Throws:

Exception - If retries are exhausted

executeWithRetry

public static <T> T executeWithRetry(Callable<T> operation,
 int maxRetries,
 Duration initialDelay,
 Predicate<Exception> retryPredicate,
 String operationName)
                              throws Exception

Retries an operation with exponential backoff.

Type Parameters:

T - Return type of the operation

Parameters:

operation - The operation to retry

maxRetries - Maximum number of retry attempts

initialDelay - Initial delay duration

retryPredicate - Condition to determine if retry should happen based on exception

Returns:

The result of the operation

Throws:

Exception - If retries are exhausted or a non-retriable exception occurs

executeWithRetry

public static <T> T executeWithRetry(Callable<T> operation,
 RetryPolicy retryPolicy,
 String operationName)
                              throws Exception

Retries an operation using a RetryPolicy.

Parameters:

operation - Operation to run

retryPolicy - Policy definition

operationName - Human-readable name for logging

Throws:

Exception
