Prompt: What does this code do?

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 | "Read Avro" >> ReadFromAvro(options.path)
       | Map(logging.info))

Response: This code reads data from Apache Avro files using the ReadFromAvro transform from the built-in AvroIO connector.

class ReadAvroOptions(PipelineOptions):

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

    options = ReadAvroOptions()

The ReadAvroOptions class defines the command-line argument --path, which specifies the path to the Avro file. To parse command-line arguments, this code uses pipeline options.

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

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

The Apache Beam pipeline uses the ReadAvroOptions class to set the path to the Avro file and the ReadFromAvro transform to read data from the file.
