Jul 1, 2025July 2025 (2025-07) – Thingsboard Gateway: SQLite Event Storage Rotation Improvements and Reliability. Implemented robust rotation for the SQLite event store, including rotation triggers for empty databases with multiple files and an on_rotate_callback to optimize rotation under high ingestion load. Reworked rotation tests for stability and reduced maintenance burden through code cleanup and targeted test improvements. These changes improve reliability of high-volume event ingestion, reduce risk of data loss, and accelerate deployment confidence. Overall impact: Enhanced stability and performance of the gateway under heavy event flow, with fewer rotation-related failures and more predictable test outcomes. This supports SLAs for data retention and system uptime in production. Technologies/skills demonstrated: SQLite storage architecture, rotation logic and optimization, test stabilization, code refactoring, and performance-oriented testing (large message payloads to stress rotation).
