April 2025 monthly summary for CDOT-CV/jpo-cvmanager: Delivered a paging-first overhaul to improve data scalability, performance, and reliability across accessors, controllers, services, and the webapp, reinforced by expanded testing and deployment readiness. Key features include converting event and notification accessors to support paging across related components, paging-enabled controllers for Event, Notification, Report, and SPAT, and applying paging patterns to core services such as ReportService and EmailTask. The webapp is now able to read paged data with field exclusions and without 206 responses, reducing payload complexity and latency. Date/time handling was improved via a date-fns upgrade and default time query expansion, while environment/deployment configurations were extended to support webapp deployment. RoadRegulatorID cleanup was performed with backward-compatibility fixes to restore stability. The testing program was expanded to cover paging changes with data-driven tests for assessment/BSM and broader event/notification/spat data-flow scenarios. Business value includes faster, more predictable data access, lower network overhead, improved stability for reporting workloads, and stronger test coverage to prevent regressions.
