Prompt: What does this code do?

class CsvOptions(PipelineOptions):
    @classmethod
    def _add_argparse_args(cls, parser):
        parser.add_argument(
            '--file_path',
            default="gs://your-bucket/your-file.csv",
            help='Csv file path'
        )


options = CsvOptions()

with beam.Pipeline(options=options) as p:
    output = (p | "Read from Csv file" >> ReadFromCsv(path=options.file_path)
    | "Log Data" >> Map(logging.info))

Response: This code reads data from a CSV file using the ReadFromCsv transform from the built-in TextIO connector.

class CsvOptions(PipelineOptions):
    @classmethod
    def _add_argparse_args(cls, parser):
        parser.add_argument(
            '--file_path',
            default="gs://your-bucket/your-file.csv",
            help='Csv file path'
        )

options = CsvOptions()

The CsvOptions class defines the command-line argument --file_path, which specifies the path to the CSV file. To parse command-line arguments, this code uses pipeline options.

with beam.Pipeline(options=options) as p:
    output = (p | "Read from Csv file" >> ReadFromCsv(path=options.file_path)
    | "Log Data" >> Map(logging.info))

The Apache Beam pipeline uses the CsvOptions class to set the CSV file path and the ReadFromCsv transform to read data from the file.
