> Support recursive reference of Avro schema
> ------------------------------------------
>
> Key: SPARK-48939
> URL: https://issues.apache.org/jira/browse/SPARK-48939
> Project: Spark
> Issue Type: New Feature
> Components: Connect
> Affects Versions: 4.0.0
> Reporter: Yuchen Liu
> Assignee: Yuchen Liu
> Priority: Major
> Labels: pull-request-available
>
> Recursive reference denotes the case that the type of a field can be defined
> before in the parent nodes. A simple example is:
> {code:java}
> {
> "type": "record",
> "name": "LongList",
> "fields" : [
> {"name": "value", "type": "long"},
> {"name": "next", "type": ["null", "LongList"]}
> ]
> }
> {code}
> This is written in Avro Schema DSL and represents a linked list data
> structure. Spark currently will throw an error on this schema. Many users
> used schema like this, so we should support it.
