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

   :: Evolving ::

   :: Evolving ::

   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`"

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

   :: Evolving ::

   :: Evolving ::

   Create a DeltaTable from the given parquet table and partition schema. Takes an existing parquet table and constructs a delta transaction log in the base path of that 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 usage would be

   io.delta.tables.DeltaTable.convertToDelta(

    Check if the provided identifier string, in this case a file path, is the root of a Delta table.
