May 2025 monthly summary for thingsboard-edge focusing on business value, reliability, and maintainability. Delivered substantive rate-limiting enhancements for Cassandra (separate Read/Write and Core/Rule Engine limits) with upgraded config management and UI labeling, alongside refactoring of the service discovery/injection path and related module relocation to improve maintainability. Strengthened reliability by fixing deduplication retry logic to respect max retries and adding targeted tests (0 and 1 retry scenarios) to prevent infinite retries. Completed branding and infrastructure refresh to Valkey, including certificate updates and module naming alignment for discovery API, which enhances security and operability across edge deployments. Augmented test coverage and maintainability through focused tests (e.g., RateLimitServiceTest), environment and resource updates, and module rename cleanup.
