Interface PartitionTracker<K,M>

All Known Subinterfaces:
JobMasterPartitionTracker, TaskExecutorPartitionTracker
All Known Implementing Classes:
AbstractPartitionTracker, JobMasterPartitionTrackerImpl, TaskExecutorPartitionTrackerImpl
public interface PartitionTracker<K,M>
Utility for tracking partitions.

This interface deliberately does not have a method to start tracking partitions, so that implementation are flexible in their definitions for this method (otherwise one would end up with multiple methods, with one part likely being unused).

  • Method Details

    • stopTrackingPartitionsFor

      Collection<PartitionTrackerEntry<K,M>> stopTrackingPartitionsFor(K key)
      Stops the tracking of all partitions for the given key.

    • stopTrackingPartitions

      Collection<PartitionTrackerEntry<K,M>> stopTrackingPartitions(Collection<ResultPartitionID> resultPartitionIds)
      Stops the tracking of the given partitions.

    • isTrackingPartitionsFor

      boolean isTrackingPartitionsFor(K key)
      Returns whether any partition is being tracked for the given key.

    • isPartitionTracked

      boolean isPartitionTracked(ResultPartitionID resultPartitionID)
      Returns whether the given partition is being tracked.
