From a90cb7f44d6ef81663b39adbd8ce9316bddc18db Mon Sep 17 00:00:00 2001 From: Francisco Javier Arceo Date: Thu, 12 Mar 2026 16:11:00 -0400 Subject: [PATCH 01/38] feat: Add version tracking to FeatureView, StreamFeatureView, and OnDemandFeatureView Every `feast apply` now creates a version snapshot. Users can pin a feature view to a specific historical version declaratively via `version="v2"`. By default, the latest version is always served. - New proto: FeatureViewVersion.proto with version record/history - Added `version` field to FeatureViewSpec, StreamFeatureViewSpec, OnDemandFeatureViewSpec and version metadata to their Meta messages - New version_utils module for parsing/normalizing version strings - Version-aware apply_feature_view in both SQL and file registries - New `list_feature_view_versions` API on FeatureStore and registries - CLI: `feast feature-views versions ` subcommand - Updated all 14 templates with explicit `version="latest"` - Unit tests (28) and integration tests (7) for versioning Co-Authored-By: Claude Opus 4.6 (1M context) --- protos/feast/core/FeatureView.proto | 11 +- protos/feast/core/FeatureViewVersion.proto | 42 +++ protos/feast/core/OnDemandFeatureView.proto | 10 +- protos/feast/core/Registry.proto | 128 ++++---- protos/feast/core/StreamFeatureView.proto | 5 +- sdk/python/feast/base_feature_view.py | 6 + sdk/python/feast/cli/feature_views.py | 44 +++ sdk/python/feast/errors.py | 10 + sdk/python/feast/feature_store.py | 12 + sdk/python/feast/feature_view.py | 17 + .../feast/infra/registry/base_registry.py | 18 ++ .../feast/infra/registry/caching_registry.py | 9 +- sdk/python/feast/infra/registry/registry.py | 150 +++++++++ sdk/python/feast/infra/registry/sql.py | 248 ++++++++++++++- sdk/python/feast/on_demand_feature_view.py | 19 ++ .../protos/feast/core/Aggregation_pb2.py | 4 +- .../protos/feast/core/Aggregation_pb2.pyi | 2 +- .../protos/feast/core/DatastoreTable_pb2.pyi | 26 +- .../feast/protos/feast/core/Entity_pb2.pyi | 26 +- .../feast/core/FeatureViewProjection_pb2.pyi | 2 +- .../feast/core/FeatureViewVersion_pb2.py | 30 ++ .../feast/core/FeatureViewVersion_pb2.pyi | 87 +++++ .../feast/core/FeatureViewVersion_pb2_grpc.py | 4 + .../protos/feast/core/FeatureView_pb2.py | 20 +- .../protos/feast/core/FeatureView_pb2.pyi | 26 +- .../feast/core/OnDemandFeatureView_pb2.py | 28 +- .../feast/core/OnDemandFeatureView_pb2.pyi | 18 +- .../feast/protos/feast/core/Project_pb2.pyi | 26 +- .../feast/protos/feast/core/Registry_pb2.py | 11 +- .../feast/protos/feast/core/Registry_pb2.pyi | 37 ++- .../feast/core/StreamFeatureView_pb2.py | 8 +- .../feast/core/StreamFeatureView_pb2.pyi | 8 +- sdk/python/feast/stream_feature_view.py | 8 + .../athena/feature_repo/test_workflow.py | 1 + .../aws/feature_repo/feature_definitions.py | 2 + .../feature_repo/feature_definitions.py | 2 + .../feature_repo/feature_definitions.py | 2 + .../gcp/feature_repo/feature_definitions.py | 2 + .../feature_repo/feature_definitions.py | 2 + .../hbase/feature_repo/feature_definitions.py | 2 + .../local/feature_repo/feature_definitions.py | 2 + .../feature_repo/feature_definitions.py | 2 + .../feature_repo/feature_definitions.py | 2 + .../pytorch_nlp/feature_repo/example_repo.py | 2 + .../ray/feature_repo/feature_definitions.py | 2 + .../snowflake/feature_repo/driver_repo.py | 2 + .../spark/feature_repo/feature_definitions.py | 2 + sdk/python/feast/version_utils.py | 51 +++ .../registration/test_versioning.py | 149 +++++++++ .../unit/test_feature_view_versioning.py | 299 ++++++++++++++++++ 50 files changed, 1456 insertions(+), 170 deletions(-) create mode 100644 protos/feast/core/FeatureViewVersion.proto create mode 100644 sdk/python/feast/protos/feast/core/FeatureViewVersion_pb2.py create mode 100644 sdk/python/feast/protos/feast/core/FeatureViewVersion_pb2.pyi create mode 100644 sdk/python/feast/protos/feast/core/FeatureViewVersion_pb2_grpc.py create mode 100644 sdk/python/feast/version_utils.py create mode 100644 sdk/python/tests/integration/registration/test_versioning.py create mode 100644 sdk/python/tests/unit/test_feature_view_versioning.py diff --git a/protos/feast/core/FeatureView.proto b/protos/feast/core/FeatureView.proto index 66dc4c3de6f..19ffe562dc8 100644 --- a/protos/feast/core/FeatureView.proto +++ b/protos/feast/core/FeatureView.proto @@ -36,7 +36,7 @@ message FeatureView { FeatureViewMeta meta = 2; } -// Next available id: 18 +// Next available id: 19 // TODO(adchia): refactor common fields from this and ODFV into separate metadata proto message FeatureViewSpec { // Name of the feature view.

Metadata-only changes (description, tags, owner, TTL, online/offline flags) update the active definition in place without creating a version. + +Schema-significant changes include: +- Adding, removing, or retyping feature columns +- Changing entities or entity columns +- Changing the UDF code (StreamFeatureView, OnDemandFeatureView) + +This keeps version history meaningful — a new version number always means a real structural change. + +### What Does NOT Trigger a New Version + +- Re-applying an identical definition (idempotent) +- Changing `description`, `tags`, `owner` +- Changing `ttl`, `online`, `offline` flags +- Changing data source paths/locations (treated as deployment config) + +### Version History Is Always-On + +Version history tracking is lightweight registry metadata — just a serialized proto snapshot per version. There is no performance cost to the online path and no additional infrastructure required. For this reason, version history is **always active** with no opt-in flag needed. + +Out of the box, every `feast apply` that changes a feature view will: +- Record a version snapshot +- Support `feast feature-views versions ` to list history +- Support `registry.list_feature_view_versions(name, project)` programmatically +- Support `registry.get_feature_view_by_version(name, project, version_number)` for snapshot retrieval +- Support version pinning via `version="v2"` in feature view definitions + +### Online Versioning Is Opt-In + +The expensive/risky part of versioning is creating **separate online store tables per version** and routing reads to them. This is gated behind a config flag: + +```yaml +registry: + path: data/registry.db + enable_online_feature_view_versioning: true +``` + +When enabled, version-qualified refs like `driver_stats@v2:trips_today` in `get_online_features()` will: +1. Look up the v2 snapshot from version history +2. Read from a version-specific online store table (`project_driver_stats_v2`) + +When disabled (the default), using `@v` refs raises a clear error. All other versioning features (history, listing, pinning, snapshot retrieval) work regardless. + +### Storage + +**File-based registry**: Version history is stored as a repeated `FeatureViewVersionRecord` message in the registry proto, alongside the existing feature view definitions. + +**SQL registry**: A dedicated `feature_view_version_history` table with columns for name, project, version number, type, proto bytes, and creation timestamp. + +### Version Pinning + +Pinning replaces the active feature view with a historical snapshot: + +```python +driver_stats = FeatureView( + name="driver_stats", + entities=[driver], + schema=[...], + source=my_source, + version="v2", # revert to v2's definition +) +``` + +Safety constraints: +- The user's feature view definition (minus the version field) must match the currently active definition. If the user changed both the schema and the version pin simultaneously, `feast apply` raises `FeatureViewPinConflict`. This prevents accidental "I thought I was reverting but I also changed things." +- Pinning does not modify version history — v0, v1, v2 snapshots remain intact. +- After a pin, removing the version field (or setting `version="latest"`) returns to auto-incrementing behavior. If the next `feast apply` detects a schema change, a new version is created. + +### Version-Qualified Feature References + +The `@v` syntax extends the existing `feature_view:feature` reference format: + +```python +features = store.get_online_features( + features=[ + "driver_stats:trips_today", # latest (default) + "driver_stats@v2:trips_today", # read from v2 + "driver_stats@v1:avg_rating", # read from v1 + ], + entity_rows=[{"driver_id": 1001}], +) +``` + +Online store table naming: +- v0 uses the existing unversioned table (`project_driver_stats`) for backward compatibility +- v1+ use suffixed tables (`project_driver_stats_v1`, `project_driver_stats_v2`) + +Each version requires its own materialization. `@latest` always resolves to the active version. + +### Supported Feature View Types + +Versioning works on all three feature view types: +- `FeatureView` / `BatchFeatureView` +- `StreamFeatureView` +- `OnDemandFeatureView` + +### Online Store Support + +Version-qualified reads (`@v`) are currently implemented for the **SQLite** online store.

The behavior depends on the version mode and registry backend. + +### `version="latest"` (auto-increment) + +The registry computes `MAX(version_number) + 1` and saves the new snapshot. If two concurrent applies race on the same version number: + +- **SQL registry**: The unique constraint on `(feature_view_name, project_id, version_number)` causes an `IntegrityError`. The registry catches this and retries up to 3 times, re-reading `MAX + 1` each time. Since the client said "latest", the exact version number doesn't matter. +- **File registry**: Last-write-wins. The file registry uses an in-memory proto with no database-level constraints, so concurrent writes may overwrite each other. This is a pre-existing limitation for all file registry operations. + +### `version="v"` (explicit version) + +The registry checks whether version N already exists: + +- **Exists** → pin/revert to that version's snapshot (unchanged behavior) +- **Doesn't exist** → forward declaration: create version N with the provided definition + +If two concurrent applies both try to forward-declare the same version: + +- **SQL registry**: The first one succeeds; the second gets a `ConcurrentVersionConflict` error with a clear message to pull latest and retry. +- **File registry**: Last-write-wins (same pre-existing limitation). + +### Recommendations + +- For single-developer or CI/CD workflows, the file registry works fine. +- For multi-client environments with concurrent applies, use the SQL registry for proper conflict detection. + +## Limitations & Future Work + +- **Online store coverage.** Version-qualified reads are only on SQLite today. Redis, DynamoDB, Bigtable, Postgres, etc. are follow-up work. +- **Offline store versioning.** This RFC covers online reads only. Versioned historical retrieval is out of scope. +- **Version deletion.** There is no mechanism to prune old versions.

Stop injecting version_tag on FeatureService projections in utils.py, which was causing non-SQLite stores to reject FeatureService reads when versioning was enabled. 2. Persist version_tag in FeatureViewProjection proto (field 10) so it survives registry round-trips. 3. Fix _update_metadata_fields() to reset current_version_number to 0 when unpinning a feature view back to version="latest". Update tests to match new behavior and add test_unpin_from_versioned_to_latest.
