Worked on the linq2db repository to deliver a cross-database IgnoreConflicts option in BulkCopyOptions, enabling safer bulk insert operations across MySQL/MariaDB, PostgreSQL, and SQLite. The approach involved standardizing conflict handling with a new ConflictAction enum and refactoring provider-specific code paths in C# to ensure consistent behavior. Refined the API by renaming OnConflictDoNothing to IgnoreConflicts and introducing a WithIgnoreConflicts helper for easier integration. Addressed build issues to restore binary compatibility and consolidated unit tests into a unified suite, improving maintainability. Demonstrated skills in C# programming, database management, and test strategy while enhancing ETL reliability and multi-database migration workflows.

Monthly summary for 2026-03 focusing on field-tested cross-database bulk operations and stability improvements. 1) Key features delivered - Implemented a cross-database IgnoreConflicts option in BulkCopyOptions to ignore conflicts during bulk copy operations across MySQL/MariaDB, PostgreSQL, and SQLite. This enables safer ETL and mass data loads by skipping conflicting rows instead of failing. - Standardized conflict handling by introducing the ConflictAction enum; renamed OnConflictDoNothing to IgnoreConflicts and added WithIgnoreConflicts helper to simplify usage across providers. - Extended provider support with concrete changes in PostgreSQLBulkCopy.cs and MySqlBulkCopy.cs to apply the new behavior consistently. 2) Major bugs fixed - Addressed build issues and restored binary compatibility to maintain a stable public API. - Fixed suppressions and consolidated tests into a single ConflictActionTests suite to improve maintainability and reliability. 3) Overall impact and accomplishments - Delivered a cross-database, safer bulk copy flow that reduces failed loads due to conflicts, enabling more reliable ETL pipelines and smoother multi-database migrations. - Unified conflict handling logic across PostgreSQL, MySQL/MariaDB, and SQLite, simplifying future enhancements and improving developer experience. 4) Technologies/skills demonstrated - C#/.NET, cross-database provider integration, BulkCopy APIs, and database-specific provider code paths. - Refactoring for binary compatibility, enum-based design for conflict handling, and test strategy consolidation. Commit note: 1c80c3e78e33963a2e75245e22552c8fb54d0ba0 (IgnoreConflicts option in BulkCopyOptions for MySql/MariaDB, PostgreSQL and SQLite) with related provider updates and tests.
