3 Commits • 1 Features
Feb 1, 2026February 2026 — microsoft/mssql-python: Major BulkCopy enhancements, authentication hardening, and parameter-mapping refactor delivering stronger security, improved developer experience, and maintainability. Key outcomes include: 1) BulkCopy API Usability and Security Enhancements with explicit parameters and type hints, 2) EntraID/Azure AD token support ensuring fresh token acquisition to prevent expired-token errors and improved auth propagation, 3) Refactor to pass all ODBC connection string parameters to py-core via a new helper (connstr_to_pycore_params) for consistent mapping and reduced duplication. Business value: safer bulk operations, clearer API surface for IDEs, more reliable token handling, easier maintenance and onboarding. Technical skills demonstrated: Python typing, API design, Azure AD integration, security hygiene, refactoring, and expanded test coverage.
