+Gluten supports inject native plan string into Spark explain with formatted mode by setting `--conf spark.gluten.sql.injectNativePlanStringToExplain=true`.

+
+Gluten supports print native plan with stats to executor system output stream by setting `--conf spark.gluten.sql.debug=true`.
+Note that, the plan string with stats is task level which may cause executor log size big. Here is an example, how Gluten show the native plan string with stats.
