> > [@FelixYBW](https://github.com/FelixYBW) Thank you for your response. My intuition is that in K8S mode, the performance of Spark tasks using local disks for shuffle is inferior to using Celeborn. Therefore, I speculate that the performance of Gluten using Celeborn will be further improved in K8S mode. > > how much time perf boost when you switch from local disk to Celeborn using jvm spark? The features benefit jvm spark can also benefit Gluten. The first graph shows the performance improvement ratio of (Spark+RSS) compared to Spark. Two SQL queries show a decrease in performance.  The second graph shows the performance improvement ratio of (Gluen+RSS) compared to Gluten. Sixteen SQL queries show a decrease in performance.  From the above two graphs, it can be observed that the trend of Gluten differs from that of Spark. After using RSS, the performance of many SQL queries in Gluten has actually decreased. Could this be due to differences in the efficiency of operations on columnar shuffle data versus row-based shuffle data? -- This is an automated message from the Apache Git Service.
