-------------------------------
Summary: document the encoding of nullable struct
Key: KAFKA-19634
URL: https://issues.apache.org/jira/browse/KAFKA-19634
Project: Kafka
Issue Type: Improvement
Reporter: Jun Rao
In [https://kafka.apache.org/protocol#protocol_types,] we didn't specify the
encoding of a struct. In particular, how a nullable struct is represented. We
should document that if a struct is nullable, the first byte indicates whether
is null and the rest of the bytes are the serialization of each field.
