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.
