Prompt: Is JSON supported in Apache Beam?

Response: JSON is a data format for storing and exchanging data. Apache Beam supports reading data from and writing data to JSON files using the ReadFromJson and WriteToJson transforms within the TextIO module. For more information, see the TextIO connector documentation in the following languages:

• Java
• Python
• Go
• Typescript

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

Here is an example of Apache Beam pipeline code for reading data from a JSON file:

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

options = JsonOptions()
with beam.Pipeline(options=options) as p:
    output = (p | "Read from Json file" >> ReadFromJson(
        path=options.file_path,
        lines=False
        )
        | "Log Data" >> Map(logging.info))
