Another design issue to notice is that the output schema may (though not usually) differ between planning-time and execution-time. In particular, the output schema depends on the aggregates, which depend on their kernels, which depend on their functions, which depend on the function registry, which may differ (or at least be incompatible for output-schema purposes) between planning-time and execution-time. Looks like the best we could do is allow the function registry to be passed in at planning-time, but this would require changing the signature of a large number of Arrow Substrait functions. -- This is an automated message from the Apache Git Service.
