Feb 1, 2025February 2025 monthly summary for green-ecolution-backend. Focused on delivering robust data querying, multi-provider support, and reliability improvements, while aggressively reducing technical debt through code cleanup and refactors. Highlights include enhancements to tree cluster data access, expanded sensor management, and more flexible scheduling, all aimed at improving scalability and operational impact across the platform. Key features delivered: - Tree Clusters Filtering: added support for filtering tree clusters and retrieving filtered counts; tests added to verify filter behavior. - Get All Function Provider Argument Usage: enabled multi-provider retrieval by using the provider argument in the getAll function. - Tree Clusters Querying, Filtering and API Response Enhancements: introduced pagination and provider attributes for cluster filtering; multi-status/region querying; refined query struct and naming; improved server response for watering status. - Sensor Data Handling and Inactive Sensor Detection: ensured sensors remain updatable when TTN data arrives; improved detection of inactive sensors using the latest data. - TTN Sensor Compatibility Enhancement: broadened sensor acceptance to support all TTN sensors. - Scheduler Enhancements: made the generic scheduler more flexible to accommodate varying workloads. Major bugs fixed: - Use update function correctly: fixed incorrect usage of the update function to ensure data consistency. - Remove statusUpdater file: cleanup of deprecated maintenance artifact. - Scheduler Context Removal: simplified scheduler interface by removing context from its struct. - Filter pagination removal: simplified filtering logic by removing pagination in filters. - Misc cleanup: removed leftover print statements for cleaner logs. - MQTT Payload struct attribute names fix: corrected MQTT payload attribute naming for alignment with updated payload formats. - Other cleanups: removal of unused and deprecated code paths (flowerbedID usage, vehicleQuery annotations, and related cleanup) to improve maintainability. Overall impact and accomplishments: - Increased data accessibility and performance for tree clusters with richer query capabilities and multi-provider support. - Improved reliability and observability through context-based logging and test coverage. - Broadened TTN integration and sensor compatibility, enabling support for a wider range of real-world devices. - Reduced technical debt via targeted cleanups and refactors, paving the way for faster iterations and lower maintenance costs. - Prepared the backend for production scale with clearer API behavior and more robust data handling. Technologies and skills demonstrated: - Go/Backend development, SQL query enhancements, and API design improvements. - Test-driven development with added test coverage for new filters. - Context-based logging and scheduler design, enabling cleaner instrumentation and easier diagnostics. - Ecosystem-wide cleanup and refactors to streamline production deployments.
