[jira] [Created] (SPARK-27407) File source V2: Invalidate cache data on overwrite/append

Gengliang Wang created SPARK-27407:
--------------------------------------

             Summary: File source V2: Invalidate cache data on overwrite/append
                 Key: SPARK-27407
                 URL: https://issues.apache.org/jira/browse/SPARK-27407
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Gengliang Wang


File source V2 currently incorrectly continues to use cached data even if the underlying data is overwritten. 
We should follow https://github.com/apache/spark/pull/13566 and fix it by invalidating and refreshes all the cached data (and the associated metadata) for any Dataframe that contains the given data source path.
