> @yma11 can you add a UI chart for the pyarrow UDF? Also add some implementation details? > > In theory we can convert Velox to Arrow in Velox pipeline, then pass the arrow pointer to Spark where it's send to python process. There is no C2R and R2C in the whole process and no memcpy between Velox and Spark. Can we achieve this? Yes. There is no C2R and R2C in current implementation. There is a VeloxColumnar to Arrow only. But for memcpy, it depends on the arrow bridge. I found there are still some memory allocation at velox for data types like string. Let me add the implementation under the feature track. -- This is an automated message from the Apache Git Service.
