@matthewmturner It is possible today to return a `Box<dyn Error>` as a `DatafusionError`which is to return a `DataFusionError::ArrowArrowError::External(Box::new(boxed_error))`. Here is an example which is pretty nasty but works that we use in IOx: https://github.com/influxdata/influxdb_iox/blob/e8ddc4e0db4c59f039a34f0e3297c9eb495c1d5a/query/src/exec/non_null_checker.rs#L271 Given how nasty that is, one alternative might be to add a `DataFusion::External` and follow the model of `ArrowError::External` in https://github.com/apache/arrow-rs/blob/master/arrow/src/error.rs#L29 Or maybe we can add a `From<Box dyn Error> for DataFusionError` to make the conversion nicer -- This is an automated message from the Apache Git Service.
