I wanted to mention that there is a proposed addition to DataFusionError, to add a `Context` variant in an open PR [1] .
The addition to DataFusionError might not be obvious as the PR is large and is largely focused on subqueries, but given the variety of opinions on Error handling in Rust in general, I felt it would be good to give some extra visibility here in case other people wanted to weigh in. Thank you, Andrew [1] https://github.com/apache/arrow-datafusion/pull/2885
