planga82 opened a new pull request #26082: [SPARK-29431][WebUI] Improve Web UI / Sql tab visualization with cached dataframes.
URL: https://github.com/apache/spark/pull/26082
 
 
   ### What changes were proposed in this pull request?
   With this pull request I want to improve the Web UI / SQL tab visualization. The principal problem that I find is when you have a cache in your plan, the SQL visualization don’t show any information about the part of the plan that has been cached.

   ### Why are the changes needed?
   When we have a SQL plan with cached dataframes we lose the graphical information of this dataframe in the sql tab
   
   ### Does this PR introduce any user-facing change?
   Yes, in the sql tab
   
   ### How was this patch tested?
   Unit testing and manual tests throught spark shell
