June 2026: Delivered two performance-oriented improvements in datahub that drive business value and reliability. 1) CI: Skip schema version bumps for no-op PDL changes, reducing CI noise and preventing unnecessary upgrades (commit c473b69e352c9493ddc748090e14d07e250ba5c2). 2) GraphQL/DB: Batch fetch in EntityAssertionsResolver to eliminate N+1 exists() calls and reduce database load (commit c7cb7468c872d466cd1c477a9417b7d7d0c90958). Impact: More reliable CI, faster query times, and more scalable data access. Technologies/skills demonstrated include Python, GraphQL, pre-commit/CICD workflows, batch data loading, and in-memory filtering for performance tuning.
