[jira] [Created] (AVRO-3307) Specify that varints should be encoded shortest possible way

Askar Safin created AVRO-3307:
---------------------------------

             Summary: Specify that varints should be encoded shortest possible way
                 Key: AVRO-3307
                 URL: https://issues.apache.org/jira/browse/AVRO-3307
             Project: Apache Avro
          Issue Type: Bug
          Components: spec
    Affects Versions: 1.11.0
            Reporter: Askar Safin


Spec is underspecified. It doesn't say whether non-canonical varint serializations are allowed (i. e. whether it is okey to serialize number "5" as two bytes). I propose to explicitly forbid such serializations. I. e. to require reader to fail when reading such serialization. This will ensure (at least for simple schemas) that equal values serialize to equal binary strings.
