6.  def coalescedJoin(leftDf: DataFrame, rightDf: DataFrame, keys: Seq[String], joinType: String = "left"): DataFrame

   * join left and right dataframes, merging any shared columns if exists by the coalesce rule.

   * join left and right dataframes, merging any shared columns if exists by the coalesce rule. fails if there is any data type mismatch between shared columns.

   The order of output joined dataframe is:

   • all keys
   • all columns on left (incl. both shared and non-shared) in the original order of left
   • all columns on right that are NOT shared by left, in the original order of right

   * Method to create a view with latest available label_ds for a given ds. This view is built on top of final label view which has all label versions available. This view will inherit the final label view properties as well.

   * Method to create or replace a view for feature table joining with labels. Label columns will be prefixed with "label" or custom prefix for easy identification

15.  def getLatestLabelMapping(tableName: String, tableUtils: TableUtils): Map[String, Seq[PartitionRange]]

    compute the mapping label_ds -> PartitionRange of ds which has this label_ds as latest version

    compute the mapping label_ds -> PartitionRange of ds which has this label_ds as latest version

    • Get all partitions from table
    • For each ds, find the latest available label_ds
    • Reverse the mapping and get the ds partition range for each label version(label_ds)

    returns

    Mapping of the label ds -> partition ranges of ds which has this label available as latest
