Package org.gridgain.internal.snapshots.tombstone

Class SnapshotTombstoneManager

java.lang.Object
org.gridgain.internal.snapshots.tombstone.SnapshotTombstoneManager
All Implemented Interfaces:
org.apache.ignite.internal.lang.Debuggable, org.apache.ignite.internal.manager.IgniteComponent
public class SnapshotTombstoneManager extends Object implements org.apache.ignite.internal.manager.IgniteComponent
Manages tombstones preserved for incremental snapshots. Every time a tombstone is created in the partition of persistent storage, it is saved to the designated tombstones storage. After a configurable timeout these tombstones are deleted.

    • startAsync

      public CompletableFuture<Void> startAsync(org.apache.ignite.internal.manager.ComponentContext componentContext)
      Specified by:
      startAsync in interface org.apache.ignite.internal.manager.IgniteComponent

    • stopAsync

      public CompletableFuture<Void> stopAsync(org.apache.ignite.internal.manager.ComponentContext componentContext)
      Specified by:
      stopAsync in interface org.apache.ignite.internal.manager.IgniteComponent

    • addOngoingIncrementalSnapshot

      public org.apache.ignite.internal.hlc.HybridTimestamp addOngoingIncrementalSnapshot(UUID snapshotId)
      Locks the upper bound for cleaning snapshot tombstones and returns the latest value. It is safe to take incremental snapshot for the tables if last snapshot for these tables was taken after this timestamp.
      Parameters:
      snapshotId - ID of the snapshot.
      Returns:
      Latest value of the low watermark.

    • removeOngoingIncrementalSnapshot

      public void removeOngoingIncrementalSnapshot(UUID snapshotId)
      Removes the snapshot's lock for the upper bound for cleaning snapshot tombstones.
      Parameters:
      snapshotId - ID of the snapshot.

    • forceClear

      @TestOnly public CompletableFuture<Void> forceClear(org.apache.ignite.internal.hlc.HybridTimestamp watermark)
      Runs the clear with specified lowWatermark.

    • ongoingIncrementalSnapshots

      @TestOnly public Set<UUID> ongoingIncrementalSnapshots()
      Returns ID's of the incremental snapshots locking low watermark.
