February 2025 monthly summary for thingsboard/thingsboard-edge focusing on business value and technical excellence. Key features delivered: - Calculated Field Processing Core Refactor and TBEL Execution Enhancements: Core refactor for calculated field processing with a new state service abstraction, TBEL argument handling improvements, partition change messaging, enhanced error handling, and environment guards to reduce runtime risk and improve maintainability. - Caching mechanism for calculated field entity profiles: Introduced a dedicated cache service to reduce database lookups and accelerate calculated field processing. - Release management and version bumps: Updated release workflow and versioning to reflect RC and final release (3.9.1-RC and 3.9.1). Major bugs fixed: - Tests and maintenance fixes for calculated fields: Fixed tests and restored missing constructor to ensure test reliability. - Stability fixes across modes: Avoided unintended startup of Kafka State Service for cores and avoided RocksDB initialization in Kafka mode, improving startup reliability and mode-specific behavior. - Additional monolith-related bug fixes: Bug fixes addressed monolith path stability and review-driven adjustments. Overall impact and accomplishments: - Improved performance and scalability of calculated field processing due to caching and refactored core logic. - Enhanced reliability and observability through better error handling, environment guards, and test infrastructure. - Streamlined release readiness with RC-to-final version bumps and improved validation. Technologies/skills demonstrated: - Java-based service refactoring, state service patterns, and TBEL execution improvements. - Caching design and integration with calculated field processing. - Conditional startup logic for Kafka vs. monolith, RocksDB interactions, and mode-specific configurations. - Test infrastructure improvements and release management practices.

January 2025 monthly summary for thingsboard/thingsboard-edge focusing on delivering business value through scalable Calculated Fields (CF) capabilities. End-to-end CF feature delivered with distributed processing, cluster mode, telemetry handling (including linked telemetry), and comprehensive entity lifecycle support. Established actor-system groundwork to enable distributed CF runtime, with ongoing refactoring of the CalculatedFieldConsumer and cluster-mode components to improve maintainability and resilience. Progressed core integrations (link dispatch, entity lifecycle) to support a cohesive CF lifecycle across services. The work lays the foundation for reliable, scalable CF at the edge and prepares for production readiness.
