PreloadedCheckpointProvider

case class PreloadedCheckpointProvider(topLevelFiles: Seq[FileStatus], lastCheckpointInfoOpt: Option[LastCheckpointInfo]) extends CheckpointProvider with DeltaLogging with Product with Serializable

An implementation of CheckpointProvider where the information about checkpoint files (i.e. Seq[FileStatus]) is already known in advance.

topLevelFiles

- file statuses that describes the checkpoint

lastCheckpointInfoOpt

- optional LastCheckpointInfo corresponding to this checkpoint. This comes from _last_checkpoint file
