> I think we can defer support for multiple consumers for the moment, I'm refactoring to singular output nodes Hmm, I'm not convinced about this. Say you have a RecordBatchReader with several columns of interest. You want each column to feed a separate execution node (say, one different scalar function per column). How do you do that if you can only have singular output nodes? Implement a "supernode" that applies multiple scalar functions to multiple columns? -- This is an automated message from the Apache Git Service.
