[jira] [Created] (SPARK-33647) cache table not working for persisted view

Linhong Liu created SPARK-33647:
-----------------------------------

             Summary: cache table not working for persisted view
                 Key: SPARK-33647
                 URL: https://issues.apache.org/jira/browse/SPARK-33647
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.1
            Reporter: Linhong Liu


In `CacheManager`, tables (including views) are cached by its logical plan, and
use `QueryPlan.sameResult` to lookup the cache. But the PersistedView wraps
the child plan with a `View` which always lead false for `sameResult` check.
