Prompt: Write the Python code to read data from JSON files using Apache Beam.

Response: Your Apache Beam pipeline can read data from JSON files using the Apache Beam TextIO connector.

import logging
import apache_beam as beam

from apache_beam import Map
from apache_beam.io.textio import ReadFromJson
from apache_beam.options.pipeline_options import PipelineOptions


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'
        )


def run():
    """
    This pipeline reads from Json file defined by the --file_path argument.
    """

    options = JsonOptions()

    with beam.Pipeline(options=options) as p:

        output = p | "Read from Json file" >> ReadFromJson(
            path=options.file_path,
            lines=False
            )


if __name__ == "__main__":
    logging.getLogger().setLevel(logging.INFO)
    run()

The JsonOptions class is a custom class that extends the PipelineOptions object. This code uses pipeline options to parse command-line arguments.

The ReadFromJson transform is a built-in Apache Beam transform that reads data from a JSON file.
