Doug Cutting commented on AVRO-1006:
------------------------------------
Raymie> SchemaFingerprint.fingerprint seems unnecessarily long...
Now this becomes
SchemaNormalization.fp(SchemaNormalization.toParsingForm(schema)). The 'fp'
might better be spelled out as 'fingerprint'. Also a utility method like
SchemaNormalization.parsingFingerprint(schema) might be useful.
Graham> pass a Normalizer instance...
With the latest API, someone can already call SchemaNormalization.fingerprint()
with a differently normalized schema, so I don't see the need for this. As we
add more normalizers to Avro we can add new methods, so I'm not (yet) seeing
the advantage of adding a Normalization interface.
