public final class NoOpTaskLocalStateStoreImpl
extends Object
implements OwnedTaskLocalStateStore

This class implements a TaskLocalStateStore with no functionality and is used when local recovery is disabled.

方法详细资料

getLocalRecoveryConfig

@Nonnull
public LocalRecoveryConfig getLocalRecoveryConfig()

从接口复制的说明: TaskLocalStateStore

Returns the LocalRecoveryConfig for this task local state store.

指定者:

getLocalRecoveryConfig 在接口中 TaskLocalStateStore

dispose

public CompletableFuture<Void> dispose()

从接口复制的说明: OwnedTaskLocalStateStore

Disposes the task local state store. Disposal can happen asynchronously and completion is signaled through the returned future.

指定者:

dispose 在接口中 OwnedTaskLocalStateStore

storeLocalState

public void storeLocalState(long checkpointId,
                            @Nullable
                            TaskStateSnapshot localState)

从接口复制的说明: TaskLocalStateStore

Stores the local state for the given checkpoint id.

指定者:

storeLocalState 在接口中 TaskLocalStateStore

参数:

checkpointId - id for the checkpoint that created the local state that will be stored.

localState - the local state to store.

retrieveLocalState

@Nullable
public TaskStateSnapshot retrieveLocalState(long checkpointID)

从接口复制的说明: TaskLocalStateStore

Returns the local state that is stored under the given checkpoint id or null if nothing was stored under the id.

指定者:

retrieveLocalState 在接口中 TaskLocalStateStore

参数:

checkpointID - the checkpoint id by which we search for local state.

返回:

the local state found for the given checkpoint id. Can be null

confirmCheckpoint

public void confirmCheckpoint(long confirmedCheckpointId)

从接口复制的说明: TaskLocalStateStore

Notifies that the checkpoint with the given id was confirmed as complete. This prunes the checkpoint history and removes all local states with a checkpoint id that is smaller than the newly confirmed checkpoint id.

指定者:

confirmCheckpoint 在接口中 TaskLocalStateStore

abortCheckpoint

public void abortCheckpoint(long abortedCheckpointId)

从接口复制的说明: TaskLocalStateStore

Notifies that the checkpoint with the given id was confirmed as aborted. This prunes the checkpoint history and removes states with a checkpoint id that is equal to the newly aborted checkpoint id.

指定者:

abortCheckpoint 在接口中 TaskLocalStateStore

pruneMatchingCheckpoints

public void pruneMatchingCheckpoints(java.util.function.LongPredicate matcher)

从接口复制的说明: TaskLocalStateStore

Remove all checkpoints from the store that match the given predicate.

指定者:

pruneMatchingCheckpoints 在接口中 TaskLocalStateStore

参数:

matcher - the predicate that selects the checkpoints for pruning.
