  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.

    Check whether the given version exists.

    Check whether the given version exists.

    mustBeRecreatable

    whether the snapshot of this version needs to be recreated.

    allowOutOfRange

    whether to allow the version is exceeding the latest snapshot version.

  11. def getActiveCommitAtTime(timestamp: Timestamp, canReturnLastCommit: Boolean, mustBeRecreatable: Boolean = true, canReturnEarliestCommit: Boolean = false): 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

    canReturnEarliestCommit

    Whether we can return the earliest commit if no such commit exists.

    Returns the latest commit that happened at or before time in the range [start, end). All the commits in the range [start, end) are assumed to not have inCommitTimestamps. If no such commit exists, the earliest commit is returned.

    Get the commit information of the Delta table from commit [start, end] in reverse chronological order. If end is None, we return all commits from start to now.

    start

    The start of the commit range, inclusive.

    end

    The end of the commit range, inclusive.

  17. def getHistory(limitOpt: Option[Int]): Seq[DeltaHistory]

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