**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** In IOx (and in DataFusion) we often want to know what the root cause of an error is (e.g was it a bug or was it a resources exhausted). ArrowError can wrap other errors with Arrow::External (and DataFusion has something similar) but there is no easy way to get at the source of the error to walk the chain without knowing all the possible types that may be present See https://github.com/apache/arrow-datafusion/blob/dde23efed94704044822bcefe49c0af7f9260088/datafusion/common/src/error.rs#L361-L439 for what we need to do now in datafusion 🤮 **Describe the solution you'd like** 1. Add DataFusionError::source() 2. Update find_root() to use that **Describe alternatives you've considered** N/A **Additional context** PR in arrow-rs: https://github.com/apache/arrow-rs/pull/3567 -- This is an automated message from the Apache Git Service.
