--------------------------------------
Summary: improve the document about "default value" of tagged
structure field
Key: KAFKA-17882
URL: https://issues.apache.org/jira/browse/KAFKA-17882
Project: Kafka
Issue Type: Improvement
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
In the [Apache Kafka
documentation|https://github.com/apache/kafka/tree/trunk/clients/src/main/resources/common/message#deserializing-messages],
we don't mention the default values for fields in tagged structures. What
happens if not all fields of a tagged structure have explicit default values?
Does the implicit default value still apply?
We should document this behavior as follows: 'A tagged structure field will be
ignored if all of its fields' values are equal to their default values,
regardless of whether those default values are defined explicitly or implicitly.
