Lucas Heimberg updated AVRO-2997:
---------------------------------
Description:
The named schema types record and enum have a documentation field. In contrast
to the Java implementation, the C# implementation of Avro is missing this field
in their canonical string representation returned by ToString().
To fix this, it seems that it is enough to add writing the documentation string
to the WriteJsonFields method of RecordSchema and EnumSchema.
This is more than a cosmetical problem as, for example, the Confluent schema
registry decides equivalence of schemas based on the canonical string
representation. The missing doc field in the C# implementation makes it hard to
emulate this concept of schema equivalence in an application using the C#
implementation of Avro.
