@comphead Thank you for your review. You're right - my current
implementation doesn't preserve backtraces.
To preserve backtraces, I think there are two options:
1. **Add Context wrapping**: We could add backtrace by using Context
```rust
let err = DataFusionError::External(Box::new($ERR))
.context(format!("backtrace: {}", DataFusionError::get_back_trace()));
```
However, this would create double wrapping and might affect error
handling logic.
2. **Modify `DataFusionError` enum definitions**: Change error variants to
include backtrace fields
```rust
External(GenericError, Option<String>),
ExecutionJoin(JoinError, Option<String>),
```
But this would need to change the usage of this error type in the
codebase
Do you think which approach is better, or would you recommend a different
solution?
