8.  def convertToDelta(spark: SparkSession, identifier: String): DeltaTable

   Create a DeltaTable from the given parquet table.

   Create a DeltaTable from the given parquet table. Takes an existing parquet table and constructs a delta transaction log in the base path of the table.

   Note: Any changes to the table during the conversion process may not result in a consistent state at the end of the conversion. Users should stop any changes to the table before the conversion is started.

   An Example would be

   io.delta.tables.DeltaTable.convertToDelta(
    spark,
    "parquet.`/path`"

   Since

   0.4.0

9.  def convertToDelta(spark: SparkSession, identifier: String, partitionSchema: String): DeltaTable
