Delta Table Checkpoint¶

Delta Table Checkpoint is a process of writing out a Snapshot of a delta table into one or more checkpoint files for faster state reconstruction (future replays of the log).

Delta Table Checkpoint happens regularly at a transaction commit every checkpoint interval or once at a transaction commit for the following commands:

• CloneTableBase
• ConvertToDeltaCommand
• RestoreTableCommand

Delta Table Checkpoint uses a Spark job called Delta checkpoint to write out checkpoint files.
