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

Response: Your Apache Beam pipeline can read data from Apache Avro files using the AvroIO connector.

import logging

import apache_beam as beam
from apache_beam import Map
from apache_beam.io.avroio import ReadFromAvro
from apache_beam.options.pipeline_options import PipelineOptions


def run(argv=None):

  class ReadAvroOptions(PipelineOptions):

    @classmethod
    def _add_argparse_args(cls, parser):
      parser.add_argument(
          "--path",
          help="GCS path to Avro file")

  options = ReadAvroOptions()

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

    (p | "ReadAvro" >> ReadFromAvro(options.path)
       | Map(logging.info))


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

The ReadAvroOptions class is used to define the command-line argument --path, which specifies the path to the Avro file. This code uses pipeline options for the required path argument.

The code creates an Apache Beam pipeline using the ReadAvroOptions class to set the Avro file path and the ReadFromAvro transform to read data from the file.
