2 Commits • 2 Features
Apr 1, 2026April 2026 focused on strengthening security, reliability, and performance for Cube.js. Delivered robust GraphQL RBAC enforcement at query execution, introduced a bypass option for visibility patching when building a shared schema, and added integration tests to verify RBAC behavior end-to-end. Implemented a safe caching strategy by building the GraphQL schema from unfiltered metadata while enforcing RBAC at query time, enabling cross-context schema reuse without compromising access controls. Hardened query validation logic in the cube orchestrator to surface hidden-member errors even on empty results and adjusted validation to exclude segments from empty-result checks. Expanded integration/Smoke tests to cover RBAC GraphQL scenarios and hidden-member behavior in edge cases. Released Cube.js v1.6.30 across packages (cube, mssql-driver, cubesql) with GraphQL cache fixes and driver enhancements, delivering a more secure, test-covered, and production-ready platform.

Jul 1, 2025July 2025 — CubeSQL stability improvements in cube-js/cube. Implemented structured handling for empty /cubesql result sets by returning the column schema and empty data, enabling predictable API responses. Fixed client-side gaps (addressing a missing CubeMetaNestedFolder in the CubeSQL client) and enhanced null handling in the native package to improve reliability. Released as v1.3.40 with focused bug fixes, aligning versioning with stability work. These changes reduce downstream parsing errors, improve integration reliability, and lay groundwork for future CubeSQL enhancements.

Nov 1, 2024Monthly summary for 2024-11: Delivered a resource-optimization improvement in the cube ecosystem by disabling Cachestore logging by default in CubeStore to save disk space. Logs are now opt-in via configuration, preserving observability while reducing storage and I/O overhead. This change supports leaner deployments and lower operational costs without impacting functionality, as logs can be re-enabled through configuration if needed.
