Summary of Changes

Hello @dhth, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new feature that allows the system to generate and upload detailed report files about the messages it processes and forwards. This enhances observability by providing a comprehensive record of each message's journey, including any decoding or upload errors. The changes involve adding new configuration options, updating internal data structures to capture more relevant metadata, and implementing a dedicated worker to manage the creation and uploading of these reports to the configured destination.

Highlights

  • Report File Uploads: Introduced functionality to generate and upload CSV report files detailing the outcome of message forwarding attempts, enhancing observability.
  • Configurability: Added new environment variables, KPLAY_FORWARD_UPLOAD_REPORTS and KPLAY_FORWARD_REPORT_BATCH_SIZE, to control report generation and batching behavior.
  • Improved Message Metadata: The internal Message struct now includes the Kafka topic and uses time.Time for timestamps, providing richer and more accurate data for processing and reporting.
  • Dynamic Content Type for Uploads: The S3 upload mechanism has been updated to accept a dynamic content type, allowing for proper handling of various file types, including the new CSV report files.
  • Increased Timeouts: Default timeouts for shutdown, Kafka polling, and message uploads have been increased to improve system robustness.

Code Review

This pull request introduces a significant new feature for uploading reports of forwarded messages. The implementation is comprehensive, adding new configuration, a dedicated reporter worker, and a CSV writer. The refactoring of types.Message to use time.Time for timestamps is a solid improvement for type safety and consistency. My review highlights a potential data loss scenario in the reporting logic, an opportunity to reduce code duplication for better maintainability, and a minor issue with error handling. Addressing these points will enhance the robustness and quality of the new feature.

Code Review

This pull request introduces a feature to generate and upload reports of forwarded messages. The implementation adds new configuration options, a dedicated reporter worker, and modifies existing components to support this. The overall approach is solid, but I've identified a high-severity bug in the new reportWriter that could lead to incorrect state management, and a medium-severity maintainability issue due to code duplication in the new reporter worker. Addressing these points will improve the robustness and clarity of the new feature.

Code Review

This pull request introduces a valuable feature for uploading reports of forwarded messages. The implementation is comprehensive, covering configuration, a new reporter worker for aggregation, and graceful shutdown handling. The code is generally well-structured, but I've identified a few areas where maintainability and robustness can be improved. My comments focus on error handling, code structure, and performance optimizations in the new worker goroutines.
