Review Comment:
I replaced the callback with the following trait:
```rust
pub trait AnalyzeObserver: Debug + Send + Sync {
/// Provides the EXPLAIN ANALYZE output (annotated plan) and the total
duration.
fn analyze_result_callback(
&self,
result: RecordBatch,
duration: std::time::Duration,
) -> Result<()>;
}
```
