             Summary: [Go][Integration] Go JSON producer generates incorrect nullable flag for nested types
                 Key: ARROW-8452
                 URL: https://issues.apache.org/jira/browse/ARROW-8452
             Project: Apache Arrow
          Issue Type: Bug
          Components: Go, Integration
            Reporter: Antoine Pitrou


It seems that when generating JSON integration data for a nested type, e.g.
"list(int32)", the list's nullable flag is also inherited by child fields. This is wrong, because child fields have independent nullable flags, e.g. you may have:
* "list(field("ints", int32, nullable=True), nullable=True)"
* "list(field("ints", int32, nullable=False), nullable=True)"
* "list(field("ints", int32, nullable=True), nullable=False)"
* "list(field("ints", int32, nullable=False), nullable=False)"
