Karen Feng created SPARK-34923:
----------------------------------
Summary: Metadata output should not always be propagated
Key: SPARK-34923
URL: https://issues.apache.org/jira/browse/SPARK-34923
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: Karen Feng
Today, the vast majority of expressions uncritically propagate metadata output
from their children. As a general rule, it seems reasonable that only
expressions that propagate their children's output should also propagate their
children's metadata output.
