Package alluxio.retry

Set of utilities for working with retryable operations. The main entrypoint is RetryPolicy which is designed to work with while loops.

Example

 {
   @code
   RetryPolicy retry = new ExponentialBackoffRetry(50, Constants.SECOND_MS, MAX_CONNECT_TRY);
   while (retry.attempt()) {
     // work to retry
   }
 }
 

Interface Summary

Interface	Description
RetryPolicy	Policy for determining whether retries should be performed, and potentially waiting for some time before the next retry attempt.
RetryUtils.RunnableThrowsIOException	Interface for methods which return nothing and may throw IOException.

Class Summary

Class	Description
CountingRetry	An option which allows retrying based on maximum count.
ExponentialBackoffRetry	Each retry will cause a sleep to happen.
ExponentialTimeBoundedRetry	A retry policy which uses exponential backoff and a maximum duration time bound.
ExponentialTimeBoundedRetry.Builder	Builder for time bounded exponential retry mechanisms.
RetryUtils	Utilities for performing retries.
SleepingRetry	A retry policy that uses thread sleeping for the delay.
TimeBoundedRetry	Retry mechanism which performs retries until a certain period of time has elapsed.
TimeoutRetry	A retry policy which allows retrying until a specified timeout is reached.
