> @guobj RAS is capable for falling back the SHJ but only with a customized cost model. Could refer to option `spark.gluten.ras.costModel` for more information. > > The final solution might involve using native SMJ which @JkSelf is working on. At this moment I think you can also try with patches @zhli1142015 has provided to see if they help. Otherwise, tuning on cost models with RAS is also a possible option. Will all fallbacks to SHJ have worse performance than vanilla spark? In other words, most of them are worse. -- This is an automated message from the Apache Git Service.
