Worked on the dbt-labs/arrow-adbc repository to enhance Databricks driver schema parsing, focusing on robust support for decimals and complex types. Leveraged Go and regular expressions to add DECIMAL(p) handling, improve Arrow schema conversion, and tighten validation logic, reducing runtime errors and improving data quality. Addressed a critical bug in decimal regex parsing to ensure accurate extraction of precision and scale, while streamlining test coverage by removing redundant cases. Emphasized schema management and data type conversion to strengthen data processing guarantees, resulting in more reliable data ingestion and improved interoperability between Databricks and Arrow-based data engineering workflows.
