November 2024
46 Commits • 8 Features
Nov 1, 2024In November 2024, PolicyEngine/policyengine-api delivery focused on data capabilities, runtime scalability, architectural modularity, and code quality. Key features delivered include dataset support within economy options with correct dataset-region dichotomy, multi-worker support with graceful exit, and a Blueprint-based routing refactor to improve modularity. Telemetry and tracing services were added to improve observability, and a broad set of code-quality and maintenance efforts (linting, changelog generation, test housekeeping) reduced technical debt and stabilized the codebase. Ongoing household endpoints migration and payload validation refactor contributed to stability and easier future evolution. Major bug fixes included reverting chunking behavior, start.sh fixes, removal of enhanced_cps as a region, and merge-conflict stabilization. Overall impact: stronger data fidelity and economy modeling, greater runtime reliability and scalability, improved observability, and lower maintenance costs. Technologies/skills demonstrated: Python/Flask blueprint architecture, dataset-region data modeling, multi-process worker orchestration, observability tooling, CI/test hygiene, and incremental refactoring for maintainability.
