Jan 1, 2025January 2025 monthly summary for thingsboard/thingsboard-edge. Focused on stabilizing edge-cloud interactions, strengthening data integrity, and improving operational reliability. Delivered three core features: Cloud Edge Connectivity and Initialization Improvements in CloudManagerService (enhanced RPC scheduling and init/partition handling); Cassandra configuration defaults aligned with Thingsboard Edge (cluster name and keyspace adjustments); Redis Lua script lazy loading with runtime SHA validation and improved logging for load/execution. Fixed critical issues: Telemetry data integrity to prevent outdated attribute overwrites (timestamp-based validation and tests); Alarm message routing fix ensuring alarm_ack/alarm_clear are routed via Push to Edge. Result: reduced data inconsistency risk, safer alert handling, and more stable release processes. Technologies/skills demonstrated: CloudManagerService architecture refinements, Cassandra configuration tuning, Redis Lua scripting with lazy loading and runtime validation, test automation stabilization, and improved observability.
