Hi, Spark friends This is Yifan. I am a software developer from Workday. I am not very familiar with Spark and I have a question about the Tag in TreeNode. We have a use case where we will add some information to Tag and we hope the tag will be persisted in Spark. But I noticed that the tag is gone when Spark creates Physical Plan from Logical Plan. Is my observation correct? Why do we not want to keep the tag from Logical Plan? Is there a good reason for that?
Look forward to your replies. Regards, Yifan
