Developed a new JDBC capability for the snowflakedb/snowflake-jdbc repository, enabling applications to access per-file result sets from COPY INTO statements through a configurable connection property. The work involved implementing the enableCopyResultSet property, updating session management logic, and ensuring robust in-session property handling. Java was used extensively, with a focus on API development and unit testing to validate the feature’s integration and prevent regressions in existing COPY workflows. This enhancement improved flexibility and observability for data copy operations, allowing users to retrieve detailed metadata via getResultSet() and supporting more advanced data tooling and workflow automation scenarios.
