[jira] [Created] (AVRO-3244) C++ Consumers cannot deserialise new enum values as per specification

Jed Robertson created AVRO-3244:
-----------------------------------

             Summary: C++ Consumers cannot deserialise new enum values as per specification
                 Key: AVRO-3244
                 URL: https://issues.apache.org/jira/browse/AVRO-3244
             Project: Apache Avro
          Issue Type: Bug
          Components: c++
    Affects Versions: 1.10.2
         Environment: C++
            Reporter: Jed Robertson


[AVRO-1340] use default to allow old readers to specify default enum value when encountering new enum symbols - ASF JIRA (apache.org) describes a useful change made a few years ago in Avro, such that enums could be expanded (an additional value(s) added) without breaking compatibility - old consumers would simply default to the default value for that enum.

Unfortunately, in C++, it appears this logic is not implemented and the consumer cannot process messages containing new enum values until it is updated.

I have: Reviewed issues related to enums, reviewied mailing list emails related to "enum" and not found any prior discussion of this issue
