  1. new DeltaHistoryManager(deltaLog: DeltaLog, maxKeysPerList: Int = 1000)

    deltaLog

    The transaction log of this table

    maxKeysPerList

    How many commits to list when performing a parallel search. Exposed for tests. Currently set to 1000, which is the maximum keys returned by S3 per list call. Azure can return 5000, therefore we choose 1000.

  10. def getActiveCommitAtTime(timestamp: Timestamp, canReturnLastCommit: Boolean, mustBeRecreatable: Boolean = true): Commit

    Returns the latest commit that happened at or before time.

    Returns the latest commit that happened at or before time.

    timestamp

    The timestamp to search for

    canReturnLastCommit

    Whether we can return the latest version of the table if the provided timestamp is after the latest commit

    mustBeRecreatable

    Whether the state at the given commit should be recreatable

  12. def getHistory(start: Long, end: Option[Long]): Seq[CommitInfo]

    Get the commit information of the Delta table from commit [start, end).

    Get the commit information of the Delta table from commit [start, end). If end is None, we return all commits from start to now.

  13. def getHistory(limitOpt: Option[Int]): Seq[CommitInfo]

    Returns the information of the latest limit commits made to this table in reverse chronological order.
