方法详细资料

cleanCheckpoint

public void cleanCheckpoint(Checkpoint checkpoint,
                            boolean shouldDiscard,
                            Runnable postCleanAction,
                            Executor executor)

addSubsumedCheckpoint

public void addSubsumedCheckpoint(CompletedCheckpoint completedCheckpoint)

Add one subsumed checkpoint to CheckpointsCleaner, the subsumed checkpoint would be discarded at cleanSubsumedCheckpoints(long, Set, Runnable, Executor).

参数:

completedCheckpoint - which is subsumed.

cleanSubsumedCheckpoints

public void cleanSubsumedCheckpoints(long upTo,
                                     Set<Long> stillInUse,
                                     Runnable postCleanAction,
                                     Executor executor)

Clean checkpoint that is not in the given .

参数:

upTo - lowest CheckpointID which is still valid.

stillInUse - the state of those checkpoints are still referenced.

postCleanAction - post action after cleaning.

executor - is used to perform the cleanup logic.

cleanCheckpointOnFailedStoring

public void cleanCheckpointOnFailedStoring(CompletedCheckpoint completedCheckpoint,
                                           Executor executor)

closeAsync

public CompletableFuture<Void> closeAsync()
