[jira] [Commented] (AVRO-2104) Schema normalisation and fingerprint support for Python 3

["Robbie Gruener (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-2104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17090746#comment-17090746 ] 

Robbie Gruener commented on AVRO-2104:
--------------------------------------

This change broke backwards compatibility with a previous serialized avro record I had which was serialized using avro-python3==1.9.0 since the fullname always included a period even if namespace was not set. Therefore I am unable to deserialize these records using avro-python3==1.9.2.1 since I get the following error:

avro.schema.SchemaParseException: Unknown named schema '.RecordName', known names: ['RecordName'].

 

Any suggestions on how to remedy this? I guess I should have used namespace but too late for that and we would like to not be stuck on avro 1.9.0 forever.

> The existing Python 3 implementation supports neither schema canonicalisation to parsing normal form, nor fingerprinting of normalised schemas. This limits the interoperability of Python 3 Avro systems with other Avro implementations including the Java and Ruby versions.
