Worked on the mathworks/arrow repository to deliver support for the Variant logical type in the Parquet C++ library. This involved implementing storage and conversion mechanisms for the new type, updating Thrift definitions, and refining the C++ type system to improve maintainability and enable future extensions. Expanded both unit and integration test coverage to ensure correctness and regression safety for variant types. The work focused on enhancing data serialization and schema definition capabilities, preparing the codebase for broader Parquet type support and downstream analytics workloads. Utilized C++ and Thrift to address interoperability challenges and align with ongoing development efforts.
