AvroIO
1. AvroIO
Avro is a file format that is self-describing. It's a very popular format for big data. AvroIO allows you to read and write to that file type. Avro files provide the schema and the data so the files can be self-describing. You can use the built-in functions from AvroIO to retrieve the schema into your Beam pipeline. You can also use wild cards to read multiple files as seen in this Python example.2. Let's practice!
