Interface BackoffStrategy

All Known Subinterfaces:
ErrorAwareBackoffStrategy
All Known Implementing Classes:
ExponentialBackoffStrategy, ExponentialErrorBackoffStrategy
public interface BackoffStrategy

Provides a way to define a back off between fetch and lock requests.

Note: Since an implementation of this interface may be executed by multiple threads, it is recommended to implement the custom backoff strategy in a thread-safe manner.

  • Method Details

    • reconfigure

      void reconfigure(List<ExternalTask> externalTasks)

      Reconfigures the back off strategy based on the fetched external tasks and is invoked before calculateBackoffTime().

      The implementation might count the amount of invocations and realize a strategy reset.

      Parameters:
      externalTasks - which have been fetched

    • calculateBackoffTime

      long calculateBackoffTime()

      Calculates the back off time and is invoked after reconfigure(List).

      Returns:
      the back off time between fetch and lock requests in milliseconds
