------------------------------------
Summary: Canonicalize With expressions by re-assigning IDs
Key: SPARK-47511
URL: https://issues.apache.org/jira/browse/SPARK-47511
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.0.0
Reporter: Kelvin Jiang
The current canonicalization of `With` expressions takes into account the ID of
the common expressions, which comes from a global monotonically increasing ID.
This means that queries with `With` expressions (e.g. `NULLIF` expressions)
will have inconsistent canonicalizations.
