> While trying to use an Avro PCollection with the SQL transform I notice you could not do correctly a bijective transform: PCollection<GenericRecord> -> SQL -> PCollection<Row> -> ParDo -> PCollection<GenericRecord> I noticed that some of the Avro metadata gets lost in particular the name of the Avro Schema. This is important because Avro validates that the schema has a name and if it does not it breaks with a ParseException.
