    Description

      It's a common pattern in big data execution engines like Beam, Spark, Flink to extract a key from an object and use it in a pipeline for later operations on grouping and aggregations.  When the Avro string primitive is a Utf8 datum, this adds unnecessary complexity because it's not serializable.

      This was mostly addressed in AVRO-200 and AVRO-1502 by making generated specific Avro objects Serializable or Externalizable, but using a STRING as a key is extremely common and worth addressing.
