Gabriel Andersson created AVRO-2363:
---------------------------------------
Summary: avro.schema.Schema in py3 prevents same record type from
being used multiple times in same schema
Key: AVRO-2363
URL: https://issues.apache.org/jira/browse/AVRO-2363
Project: Apache Avro
Issue Type: Bug
Components: python
Affects Versions: 1.9.0
Reporter: Gabriel Andersson
After mostly worked in Java with avro, schemas have been used in an hierachial
way. I.e. Schema A imports Schema B and Schema C, Schema B imports schema C.
This works in a confluent setting. But when loading the schema, the application
crashes due to reusing record types.
The following relaxes this relation.
