[jira] [Commented] (AVRO-3968) Support for custom @AvroNamespace annotation

["Oscar Westra van Holthe - Kind (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-3968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17834679#comment-17834679 ] 

Oscar Westra van Holthe - Kind commented on AVRO-3968:
------------------------------------------------------

Though I appreciate the request for an {{@AvroNamespace}} annotation, I'd prefer to extend the applicability of the {{@AvroName}} annotation to include classes.

 

This would work as follows:
 # {{@AvroName("fieldName")}} on a field would name the field only (this is the current situation)
 # {{@AvroName(value="fieldName", namespace="my.space")}} on a field would trigger an error: fields have no namespace
 # Using {{@AvroName}} on a class that does not become a named type would trigger an error
 # {{@AvroName("simpleOrFullName")}} for a named type would set its name, optionally with namespace
 # {{@AvroName(value="simpleName", namespace="my.space")}} for a named type would set its name and namespace
 # {{@AvroName(namespace="my.space")}} for a named type would set only the namespace and let the name be inferred

 

Would this work for you as well? Or would an {{@AvroTypeName}} be a better annotation for types?

>            Priority: Major
>
> Currently there are several java annotations like @AvroSchema, @AvroName, @AvroDoc etc that can be used to decorate Java POJO classes which in turn are used when generating avro schema with reflection.
> While @AvroName annotation comes handy for overriding the name of fields, there is no support for overriding the namespace.
>  
> Currently by default the java POJO's package name is used as the namespace. This is a bit restrictive as there can be cases where we may want to generate the schema with a different namespace.
>  
> The ask over here is to provide a @AvroNamespace annotation that can let us override the namespace to what we intend to.
>  
> Happy to contribute with a PR for the same.
