Description: Summary Adds automatic version tracking to Feast feature views (FeatureView, StreamFeatureView, OnDemandFeatureView). Every feast apply that changes a feature view's schema or UDF creates a versioned snapshot in the registry. Users can list version history, pin serving to a prior version, query specific versions via @v syntax, and stage new versions without promoting them. Resolves #2728 Key Features Automatic version history — every schema/UDF change is tracked; metadata-only changes (description, tags, TTL) update in place without creating a new version Version pinning — declaratively pin to a historical version: FeatureView(name="driver_stats", version="v2") Version-qualified online reads — query specific versions: driver_stats@v2:trips_today (SQLite online store) Staged publishing (--no-promote) — feast apply --no-promote saves a new version without promoting it to active, enabling phased rollouts without a transition window Version-aware materialization — feast materialize --views fv --version v2 targets a specific version's online store table Feature service support — feature services automatically resolve versioned FVs when enable_online_feature_view_versioning is enabled Pin conflict detection — prevents applying a schema change and version pin simultaneously Concurrent apply safety — SQL registry uses unique constraints with retry; file registry is last-write-wins (pre-existing limitation) Full backward compatibility — version is optional; omitting it is identical to version="latest" Changes Proto layer: New FeatureViewVersion.proto with FeatureViewVersionRecord / FeatureViewVersionHistory Added version field to FeatureViewSpec, StreamFeatureViewSpec, OnDemandFeatureViewSpec Added current_version_number to meta messages, version_tag to FeatureViewProjection Added feature_view_version_history to Registry proto Python SDK — core versioning: version_utils.py — parses "latest", "v2", "version2" (case-insensitive) version parameter on FeatureView, StreamFeatureView, OnDemandFeatureView Version-aware apply_feature_view in file registry, SQL registry (with concurrent apply retry) list_feature_view_versions(name, project) on registries and FeatureStore get_feature_view_by_version(name, project, version_number) for explicit version lookup _schema_or_udf_changed() to distinguish version-significant changes from metadata updates Python SDK — --no-promote flag: feast apply --no-promote CLI option threaded through apply_total() → apply_total_with_repo_instance() → store.apply() / store._apply_diffs() → registry.apply_feature_view() File registry: saves version snapshot, restores old active proto SQL registry: saves version snapshot, skips active row UPDATE Python SDK: store.apply([...], no_promote=True) Python SDK — version-qualified reads: _parse_feature_ref() and _strip_version_from_ref() utilities for fv@v:feature parsing Version-aware online feature retrieval with @v syntax Version metadata injection in online feature responses Feature service version resolution with version_tag on projections Python SDK — feature ref parsing audit & fixes: Fixed ibis offline store prefix matching to use name_to_use() for versioned refs Fixed passthrough_provider.py saved dataset column naming to strip @v Fixed Go ParseFeatureReference to strip @v from feature view name CLI: feast feature-views versions — list version history feast apply --no-promote — stage versions without promoting feast materialize --views --version v — version-aware materialization UI: Version display on feature view detail pages (Regular, Stream, OnDemand) New "Versions" tab showing version history with timestamps Documentation: RFC: docs/rfcs/feature-view-versioning.md — full design, concurrency, feature services, staged publishing Alpha reference: docs/reference/alpha-feature-view-versioning.md Updated feature view concepts page with [Alpha] Versioning section Updated CLI reference, retrieval docs, and SUMMARY.md Test plan 47 unit tests: version parsing, normalization, proto roundtrip, equality, copy, feature ref parsing, table ID generation 37 integration tests: apply/version creation, idempotency, pinning, pin conflicts, forward declaration, schema vs metadata changes, stream FV UDF changes, version metadata, feature service gates, --no-promote (5 tests) Pre-commit hooks pass (format, lint, detect-secrets) mypy type checking passes on all modified files CI: existing unit tests pass (no regressions) UI Preview 🤖 Generated with Claude Code
