PROFILE

Dan Liu

Over four months, contributed core features to cloud data integration and API projects, focusing on Snowflake and ADBC driver enhancements. In the apache/arrow-adbc repository, implemented a nullable AdbcCommandTimeoutProperty in C#, allowing CommandTimeout to function independently of driver configuration and reducing runtime errors. Enhanced API documentation and developer onboarding in mikeharder/azure-rest-api-specs by adding Swagger support for Snowflake Script multi-resultset queries and clarifying endpoint descriptions using YAML and Swagger. Expanded SnowflakeV2 data type support in welovej/azure-rest-api-specs, collaborating across teams to improve integration versatility. Work emphasized maintainability, cross-platform consistency, and robust API development using C# and Python.

In April 2026, delivered a core feature for the apache/arrow-adbc project: making AdbcCommandTimeoutProperty optional so CommandTimeout can function without the property. Previously, CommandTimeout required AdbcCommandTimeoutProperty and could throw InvalidOperationException if not configured (notably in Snowflake). The new approach makes AdbcCommandTimeoutProperty nullable; CommandTimeout stores the value locally when no driver property is configured and only propagates to the driver via SetOption when the property is set. This increases driver-configuration flexibility, reduces runtime errors, and improves cross-driver timeout consistency across the ADBC stack.
