case class LogSegment(logPath: Path, version: Long, deltas: Seq[FileStatus], checkpoint: Seq[FileStatus], checkpointVersionOpt: Option[Long], lastCommitTimestamp: Long) extends Product with Serializable
Provides information around which files in the transaction log need to be read to create the given version of the log.
- logPath
The path to the _delta_log directory
- version
The Snapshot version to generate
- deltas
The delta commit files (.json) to read
- checkpoint
The checkpoint file to read
- checkpointVersionOpt
The checkpoint version used to start replay
- lastCommitTimestamp
The "unadjusted" timestamp of the last commit within this segment. By unadjusted, we mean that the commit timestamps may not necessarily be monotonically increasing for the commits within this segment.
