Worked on the apache/datafusion repository to enable external-system usage of DataFusion logical plans by implementing protobuf-based serialization for EmptyTable scans. This involved refactoring core modules for improved portability, moving EmptyTable into datafusion-catalog while maintaining backwards compatibility, and introducing a new EmptyTableScanNode protobuf definition. The developer integrated encoding and decoding logic into the logical plan node pipeline, ensuring that plans could be serialized and deserialized for use in Python bindings and gRPC-based executors. Comprehensive roundtrip tests were added to validate the new serialization pathway, leveraging Rust, Protobuf, and gRPC to enhance cross-system interoperability for VegaFusion-style scenarios.
