April 2026 monthly summary for opendatahub-io/feast: - Focused on hardening data isolation in a multi-tenant environment by adding a project_id-scoped UPDATE path for SnowflakeRegistry, preventing cross-project overwrites in a shared registry. The UPDATE path now mirrors the existing project_id scoping of the SELECT and DELETE paths, ensuring consistent data integrity across projects. - Implemented as part of the SnowflakeRegistry changes (commit 6658b71b1786289cb3189bf90204d6e1fbef5210) and accompanied by automated tests to validate cross-project isolation and prevent regressions (e.g., test_apply_object_does_not_overwrite_sibling_project). The changes fix the regression reported in #6208. - Maintained and enhanced test quality with linting and formatting improvements, ensuring code health and easier future maintenance. Business value: These changes reduce the risk of data corruption in a shared registry, enabling safe multi-tenant usage, improving reliability for downstream deployments and analytics that rely on Feast’s Snowflake-backed registry. Technologies/skills demonstrated: Python (registry logic), SQL filtering in UPDATE clauses, test-driven development, multi-tenant data isolation patterns, lint/format governance (ruff), CI test suite health, packaging and repository hygiene.
