  8. def convertColumnTypeToSparkSQLDataType(columnType: TypeValue): (DataType, Option[String])

  9. def convertSparkSQLDataTypeToColumnType(structField: StructField): ColumnDef

    Converts from a Spark SQL struct field to an Alpine-specific column def.

  10. def convertSparkSQLDataTypeToColumnType(dataType: DataType): TypeValue

    Converts from a Spark SQL data type to an Alpine-specific column type.

  11. def convertSparkSQLSchemaToTabularSchema(schema: StructType): TabularSchema

    Converts from a Spark SQL schema to the Alpine 'TabularSchema' type.

    Converts from a Spark SQL schema to the Alpine 'TabularSchema' type. The 'TabularSchema' object this method returns can be used to create any of the tabular Alpine IO types (HDFSTabular dataset, dataTable etc.)

    schema

    -a Spark SQL DataFrame schema

    returns

    the equivalent Alpine schema for that dataset

  12. def convertTabularSchemaToSparkSQLSchemaDateSupport(tabularSchema: TabularSchema): (StructType, Map[String, String])

    Convert the Alpine 'TabularSchema' with column names and types to the equivalent Spark SQL data frame header.

    Convert the Alpine 'TabularSchema' with column names and types to the equivalent Spark SQL data frame header.

    tabularSchema

    An Alpine 'TabularSchemaOutline' object with fixed column definitions containing a name and Alpine specific type.
