Interesting result. I was also somehow expecting the codegen path to have some advantage. One reason, I suspect is that the performance is dependent on the time spent in moving data over the jvm boundary. `Platform.getInt(null, addr + rowId * 4L)` is simply moving data from offheap into a jvm variable and since both approaches incur this cost, we are seeing nearly identical performance. -- This is an automated message from the Apache Git Service.
