This project does not create a new feature flag; it just reuses the existing featureFlagSbeFull flag. The enabling or disabling of this flag does not require upgrade/downgrade testing as it has no impact other than selecting which execution engine (Classic or SBE) affected queries will be run in. There is already extensive testing in patch builds and Evergreen nightly runs of both cases (flag enabled and disabled), so we have confidence in the correctness and performance of both engines for the affected queries. |
