Interface Summary

Interface	Description
CheckpointListener	Listener which methods will be called in a corresponded checkpoint life cycle period.
CheckpointListener.Context	Context with information about current snapshots.
CheckpointPagesWriter.CheckpointPageWriter	Interface which allows to write one page to page store.
CheckpointProgress	Represents information of a progress of a current checkpoint and allows to obtain future to wait for a particular checkpoint state.

Class Summary

Class	Description
CheckpointContextImpl	Context with information about current checkpoint.
CheckpointEntry	Class represents checkpoint state.
CheckpointEntry.GroupState
CheckpointEntry.GroupStateLazyStore	Group state lazy store.
Checkpointer	Checkpointer object is used for notification on checkpoint begin, predicate is Checkpointer.scheduledCp.nextCpTs - now > 0 .
CheckpointHistory	Checkpoint history.
CheckpointHistoryResult	Result of a checkpoint search and reservation.
CheckpointManager	Main class to abstract checkpoint-related processes and actions and hide them from higher-level components.
CheckpointMarkersStorage	Abstraction responsible for managing checkpoint markers storage.
CheckpointPagesInfoHolder	Snapshot of dirty pages which should be stored to disk.
CheckpointPagesWriter	Implementation of page writer which able to store pages to disk during checkpoint.
CheckpointPagesWriterFactory	Factory class for checkpoint pages writer.
CheckpointProgressImpl	Data class representing the state of running/scheduled checkpoint.
CheckpointReadWriteLock	Wrapper of the classic read write lock with checkpoint features.
CheckpointStatus	Checkpoint status which was restored from disk on node start.
CheckpointTimeoutLock	Checkpoint lock for outer usage which should be used to protect data during writing to memory.
CheckpointWorkflow	This class responsibility is to complement Checkpointer class with side logic of checkpointing like checkpoint listeners notifications, WAL records management and checkpoint markers management.
LightweightCheckpointManager	Like a sharp checkpoint algorithm implemented in CheckpointManager this checkpoint ensures that all pages marked dirty under LightweightCheckpointManager.checkpointTimeoutLock() will be consistently saved to disk.
PartitionDestroyQueue	Partition destroy queue.
PartitionDestroyRequest	Partition destroy request.

Enum Summary

Enum	Description
CheckpointEntryType	Checkpoint entry types.
ReservationReason	Represent a reason by that a WAL history was bounded.
