Summary: Kafka Connect Schema Compatibility Checks for Name Changes Key: KAFKA-8553 URL: https://issues.apache.org/jira/browse/KAFKA-8553 Project: Kafka Issue Type: Bug Components: KafkaConnect Reporter: Omer van Kloeten {{SchemaProjector.checkMaybeCompatible}} checks whether the Connect schema is compatible with another one. This is used for projection when using {{schema.compatibility}}. Unfortunately, nowhere is it documented that if you change the name of the schema, this would break compatibility entirely. For instance, the following two Avro schemas are fully compatible, but Connect says they're not: {{{}} {{ "type": "record",}} {{ "name": "Foo1",}} {{ "namespace":"example",}} {{ "fields": [}} {{ ]}} {{ }}} {{{}} {{ "type": "record",}} {{ "name": "Foo2",}} {{ "namespace":"example",}} {{ "fields": [}} {{ {"name": "bar", "type": ["null", "string"]}}} {{ ]}} {{}}} This is either the expected behavior and is not documented or unexpected behavior and is a bug. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
