### Is your feature request related to a problem or challenge? `ExecutionPlan::partition_statistics()` is not currently reachable through datafusion-ffi: `FFI_ExecutionPlan` exposes most of the trait (`properties`, `children`, `with_new_children`, `name`, `execute`, `repartitioned`, and [soon `metrics`](https://github.com/rerun-io/reality/pull/1977)) but has no function pointer for `partition_statistics()`, so `ForeignExecutionPlan::partition_statistics()` falls through to the trait default implementation and always returns `Statistics::new_unknown()`. ### Describe the solution you'd like Expose `partition_statistics()` across the FFI boundary by serializing the Statistics struct using protobuf, similar to how filters are currently handled. This avoids creating a parallel type system. ### Describe alternatives you've considered Create a mapping/conversion layer from the current Statistics type to FFI-safe types. Rejected: it requires defining many type variants and protobuf serialization results in much less code. ### Additional context I have a PR already authored. This will be a breaking change requiring a major version bump. -- This is an automated message from the Apache Git Service.
