Prompt: Is CSV format supported in Apache Beam?

Response: CSV is a data format for storing and exchanging data. Apache Beam supports reading data from and writing data to CSV files using the ReadFromText and WriteToText transforms in the TextIO module. For more information, see the TextIO connector documentation:

• Java
• Python
• Go
• Typescript

To get started with CSV and Apache Beam, refer to the Dataflow Cookbook GitHub repository.

Here's an example of Apache Beam pipeline code for reading data from a CSV file:

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))
