方法详细资料

allocationBaseDirectory

public File allocationBaseDirectory(long checkpointId)

从接口复制的说明: LocalSnapshotDirectoryProvider

Returns the local state allocation base directory for given checkpoint id w.r.t. our rotation over all available allocation base directories.

指定者:

allocationBaseDirectory 在接口中 LocalSnapshotDirectoryProvider

subtaskBaseDirectory

public File subtaskBaseDirectory(long checkpointId)

从接口复制的说明: LocalSnapshotDirectoryProvider

Returns the local state directory for the owning subtask the given checkpoint id w.r.t. our rotation over all available available allocation base directories. This directory is contained in the directory returned by LocalSnapshotDirectoryProvider.allocationBaseDirectory(long) for the same checkpoint id.

指定者:

subtaskBaseDirectory 在接口中 LocalSnapshotDirectoryProvider

subtaskSpecificCheckpointDirectory

public File subtaskSpecificCheckpointDirectory(long checkpointId)

从接口复制的说明: LocalSnapshotDirectoryProvider

Returns the local state directory for the specific operator subtask and the given checkpoint id w.r.t. our rotation over all available root dirs. This directory is contained in the directory returned by LocalSnapshotDirectoryProvider.subtaskBaseDirectory(long) for the same checkpoint id.

指定者:

subtaskSpecificCheckpointDirectory 在接口中 LocalSnapshotDirectoryProvider

selectAllocationBaseDirectory

public File selectAllocationBaseDirectory(int idx)

从接口复制的说明: LocalSnapshotDirectoryProvider

Returns a specific allocation base directory. The index must be between 0 (incl.) and LocalSnapshotDirectoryProvider.allocationBaseDirsCount() (excl.).

指定者:

selectAllocationBaseDirectory 在接口中 LocalSnapshotDirectoryProvider

selectSubtaskBaseDirectory

public File selectSubtaskBaseDirectory(int idx)

从接口复制的说明: LocalSnapshotDirectoryProvider

Returns a specific subtask base directory. The index must be between 0 (incl.) and LocalSnapshotDirectoryProvider.allocationBaseDirsCount() (excl.). This directory is direct a child of LocalSnapshotDirectoryProvider.selectSubtaskBaseDirectory(int) given the same index.

指定者:

selectSubtaskBaseDirectory 在接口中 LocalSnapshotDirectoryProvider

allocationBaseDirsCount

public int allocationBaseDirsCount()

从接口复制的说明: LocalSnapshotDirectoryProvider

Returns the total number of allocation base directories.

指定者:

allocationBaseDirsCount 在接口中 LocalSnapshotDirectoryProvider
