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.
