  10. def getStartingVersionFromTimestamp(spark: SparkSession, deltaLog: DeltaLog, timestamp: Timestamp, canExceedLatest: Boolean = false): Long

    - If a commit version exactly matches the provided timestamp, we return it.

    - If a commit version exactly matches the provided timestamp, we return it. - Otherwise, we return the earliest commit version with a timestamp greater than the provided one. - If the provided timestamp is larger than the timestamp of any committed version, and canExceedLatest is disabled we throw an error. - If the provided timestamp is larger than the timestamp of any committed version, and canExceedLatest is enabled we return a version that is greater than deltaLog.snapshot.version by one

    spark

    - current spark session

    deltaLog

    - Delta log of the table for which we find the version.

    timestamp

    - user specified timestamp

    canExceedLatest

    - if true, version can be greater than the latest snapshot commit

    returns

    - corresponding version number for timestamp
