May 2025 performance highlights: two high-impact feature efforts across two repos focused on reliability, observability, and security. Key features delivered: 1) AWS SDK v4 upgrade in NServiceBus.AmazonSQS with reliability improvements for SQS/SNS, including null checks, message pumping fixes, and updated policy management. 2) Logging and Observability Enhancements for NServiceBus.TransactionalSession, delivering improved control-message logs, clearer conditions for delaying/consuming, and more informative messages to aid debugging and configuration. Major bugs fixed: stability and reliability issues addressed by the SDK upgrade and enhanced diagnostics via logging, improving error visibility and maintainability. Overall impact and accomplishments: Reduced risk in SQS/SNS interactions, faster issue diagnosis, and improved maintainability of two critical subsystems. Technologies/skills demonstrated: AWS SDK v4, .NET/C#, NServiceBus, SQS/SNS integration, advanced logging and observability, and security policy management.

In April 2025, the team delivered reliability and sizing improvements for the Particular/ServiceControl SQS transport. By upgrading the SQS dependency and introducing a Reserved Bytes configuration, message size calculations became more accurate and flexible, reducing waste and the risk of oversized messages. In addition, automatic visibility renewal for messages was disabled to avoid processing delays and delivery issues, improving stability in high-throughput scenarios.

March 2025 monthly summary for Particular/NServiceBus.AmazonSQS. Delivered a new transport configuration option, ReserveBytesInMessageSizeCalculation, to improve message size calculations by reserving extra bytes for payloads. This addresses SQS size constraints and enables larger payloads to be uploaded to S3 when needed. Updated tests and internal message preparation logic to incorporate the new setting. No major bugs reported for this repository in the period. Overall impact: increased reliability and configurability for large-payload scenarios, reducing failed messages due to size limits and enabling more scalable messaging workflows. Key skills demonstrated include C#/.NET, NServiceBus AmazonSQS transport, test-driven development, configuration design, and maintainable code changes.
