Apr 1, 2026April 2026: Focused on strengthening reliability and cross-partition transactional capabilities in the Cosmos DB .NET v3 SDK. Delivered major Distributed Transactions API enhancements (including end-to-end DTS with stream variants and distributed read transactions), hardened data contracts with mandatory documentId, and standardized serialization via shared constants and camelCase naming. Introduced a public API surface for distributed reads (CosmosClient.CreateDistributedReadTransaction) and core implementation (DistributedReadTransactionCore). Fixed ReadSessionNotAvailable by merging per-operation session tokens into the SessionContainer after commits. Expanded tests and refactors to improve coverage and maintainability. Business impact: safer cross-partition transactions, fewer runtime errors, and more predictable developer experience. Technologies demonstrated: C#, .NET, JSON serialization, constants-based naming, and distributed transaction patterns.

Jan 1, 2026January 2026 monthly summary for Azure/azure-cosmos-dotnet-v3: Focused on delivering cross-partition distributed transactions in Cosmos DB to ensure atomic multi-write operations across partitions and containers. Implemented support for distributed transactions that can encapsulate multiple writes (create, replace, delete, upsert) across different partitions within a single transaction, improving data consistency and integrity for distributed workloads. The work reduces reconciliation overhead and simplifies complex multi-entity operations for enterprise apps. The feature is implemented with a dedicated commit referenced below and is ready for integration testing and adoption. Commit reference: d6a69c8ee8e14a7290f3a89d768057ffa80552ed.
