By design, a composable data system architecture provides the flexibility to use many execution paradigms. At Voltron Data, to prove this out, we are developing an execution system that uses the same logical plans on both CPU and GPU executors: (1) GPU executor is RAPIDS cuDF from NVIDIA, and (2) the CPU executor is Velox from Meta. The number of FLOPs is steadily increasing and the costs for memory is decreasing quickly [1], [2].
