> SPARK-29894 provides information on the Codegen Stage Id in WEBUI for SQL Plan graphs. Similarly, this proposes to add Codegen Stage Id in the DAG visualization for Stage execution. DAGs for Stage execution are available in the WEBUI under the Jobs and Stages tabs.
> This is proposed as an aid for drill-down analysis of complex SQL statement execution, as it is not always easy to match parts of the SQL Plan graph with the corresponding Stage DAG execution graph. Adding Codegen Stage Id for WholeStageCodegen operations makes this task easier.
