  4. val LAST_CHECKPOINT: Path

    The path to the file that holds metadata about the most recent checkpoint.

  6. def checkpoint(snapshotToCheckpoint: Snapshot): Unit

    Creates a checkpoint using snapshotToCheckpoint.

    Creates a checkpoint using snapshotToCheckpoint. By default it uses the current log version. Note that this function captures and logs all exceptions, since the checkpoint shouldn't fail the overall commit operation.

  7. def checkpointAndCleanUpDeltaLog(snapshotToCheckpoint: Snapshot): Unit
  8. def checkpointInterval(metadata: Metadata): Int

    Returns the checkpoint interval for this log.

    Returns the checkpoint interval for this log. Not transactional.

  10. def createCheckpointAtVersion(version: Long): Unit

    Creates a checkpoint at given version.

    Creates a checkpoint at given version. Does not invoke metadata cleanup as part of it.

    version

    - version at which we want to create a checkpoint.

  11. def deltaAssert(check: ⇒ Boolean, name: String, msg: String, deltaLog: DeltaLog = null, data: AnyRef = null, path: Option[Path] = None): Unit

    Helper method to check invariants in Delta code.

    Helper method to check invariants in Delta code. Fails when running in tests, records a delta assertion event and logs a warning otherwise.

  15. def findLastCompleteCheckpointBefore(checkpointInstance: Option[CheckpointInstance] = None): Option[CheckpointInstance]

    Finds the first verified, complete checkpoint before the given CheckpointInstance.

    Finds the first verified, complete checkpoint before the given CheckpointInstance. If checkpointInstance is passed as None, then we return the last complete checkpoint in the deltalog directory.

    checkpointInstance

  16. def findLastCompleteCheckpointBefore(version: Long): Option[CheckpointInstance]

    Finds the first verified, complete checkpoint before the given version.

    Finds the first verified, complete checkpoint before the given version. Note that the returned checkpoint will always be < version.

    version

    The checkpoint version to compare against
