-----------------------------------------
Summary: AvroTypeInfo requires objects to be strict POJOs
(mutable, with setters)
Key: FLINK-13703
URL: https://issues.apache.org/jira/browse/FLINK-13703
Project: Flink
Issue Type: Improvement
Reporter: Alexander Fedulov
There exists an option to generate Avro sources which would represent immutable
objects (`createSetters` option set to false)
[1|https://github.com/commercehub-oss/gradle-avro-plugin] , [2|
https://avro.apache.org/docs/current/api/java/org/apache/avro/mojo/AbstractAvroMojo.html].
Those objects still have full arguments constructors and are being correctly
dealt with by Avro.
`AvroTypeInfo` in Flink performs a check to verify if a Class complies to the
strict POJO requirements (including setters) and throws an
IllegalStateException("Expecting type to be a PojoTypeInfo") otherwise. Can
this check be relaxed to provide better immutability support?
+Steps to reproduce:+
1) Generate Avro sources from schema using `createSetters` option.
2) Use generated class in
`ConfluentRegistryAvroDeserializationSchema.forSpecific(GeneratedClass.class,
schemaRegistryUrl)`
