Class	Description
CheckpointCoordinator	The checkpoint coordinator coordinates the distributed snapshots of operators and state.

PendingCheckpoint	A pending checkpoint is a checkpoint that has been started, but has not been acknowledged by all tasks that need to acknowledge it.
SavepointCoordinator	The savepoint coordinator is a slightly modified variant of the regular checkpoint coordinator.
SavepointCoordinatorDeActivator	This actor listens to changes in the JobStatus and deactivates the savepoint scheduler and discards all pending checkpoints.
SavepointStore	Simple wrapper around the state store for savepoints.
SavepointStoreFactory	Factory for savepoint StateStore instances.
StandaloneCheckpointIDCounter	CheckpointIDCounter instances for JobManagers running in RecoveryMode.STANDALONE.
StandaloneCheckpointRecoveryFactory	CheckpointCoordinator components in RecoveryMode.STANDALONE.
StateForTask	Simple bean to describe the state belonging to a parallel operator.
ZooKeeperCheckpointIDCounter	CheckpointIDCounter instances for JobManagers running in RecoveryMode.ZOOKEEPER.
ZooKeeperCheckpointRecoveryFactory	CheckpointCoordinator components in RecoveryMode.ZOOKEEPER.
ZooKeeperCompletedCheckpointStore	CompletedCheckpointStore for JobManagers running in RecoveryMode.ZOOKEEPER.
