Over two months, Bitter Polders enhanced the TobikoData/sqlmesh repository by delivering robust backend features and a targeted bug fix. They improved data catalog security and deployment flexibility by adding configurable data paths and encryption options to the DuckLake catalog, updating Python configuration classes, SQL integration, and documentation. For MSSQL support, Bitter Polders extended connectivity to include pyodbc, refactored driver configurations, and standardized SQL keyword handling, streamlining cross-driver compatibility. In July, they addressed a data accuracy issue by implementing custom output converters in Python to correctly parse MSSQL DATETIMEOFFSET types, ensuring reliable, timezone-aware data processing for analytics pipelines.

Jun 1, 2025June 2025 monthly summary for TobikoData/sqlmesh: Delivered feature enhancements to improve data catalog security and MSSQL connectivity, resulting in greater deployment flexibility and reliability. DuckLake Catalog Configuration Enhancements enable specifying a data path and encryption settings, with updated documentation, configuration classes, and tests. MSSQL Integration Improvements extend support to pyodbc alongside pymssql, refactor driver/ODBC configurations, and provide Azure SQL/AD authentication guidance; MSSQL engine adapter now standardizes SQL keywords to uppercase for consistency. These changes reduce setup friction, improve security posture, and enhance cross-driver compatibility, enabling teams to build more secure, scalable data pipelines. Key achievements: - DuckLake Catalog Configuration Enhancements: added data path and encryption options; docs, config classes, and tests updated - MSSQL Integration Improvements: added pyodbc support in addition to pymssql; updated docs for installation and AD authentication; refactored connection configuration for different drivers and ODBC strings - MSSQL Engine Quality: standardized SQL keywords to uppercase in the MSSQL adapter - Documentation and Testing: updated docs and tests to reflect new options and configurations
