Github user rednaxelafx commented on the issue: https://github.com/apache/spark/pull/22187 So the new solution now is to directly ship the `StructType` object as a reference object. Why not? ;-) I'm +1 on shipping the object directly instead of generating code to recreate it on the executor. If other reviewers are also on board with this approach, let's update the PR title and the JIRA ticket title to reflect that (since we're no longer generating any "names" at all now).
