Parquet. Scio supports reading and writing Parquet files as Avro records or Scala case classes. Also see Avro page on reading and writing regular Avro files.. Avro Read Parquet files as Avro The AvroParquetWriter already depends on Hadoop, so even if this extra dependency is unacceptable to you it may not be a big deal to others: You can use an AvroParquetWriter to stream directly to S3 by passing it a Hadoop Path that is created with a URI parameter and setting the proper configs. GitHub Gist: star and fork hammer's gists by creating an account on GitHub.
