gengliangwang opened a new pull request #24318: [SPARK-27407][SQL] File source V2: Invalidate cache data on overwrite/append
URL: https://github.com/apache/spark/pull/24318
 
 
   ## What changes were proposed in this pull request?
   
   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.
   
   
   ## How was this patch tested?
   
   Unit test
