fix: Allow dill 0.4 so UDF serialization works on Python 3.14 by YHC66 · Pull Request #6858 · feast-dev/feast

YHC66 · 2026-09-22T21:52:34Z

What this PR does / why we need it:

dill~=0.3.0 keeps Python 3.14 users on dill 0.3.9, which doesn't support 3.14's changes to pickle. Serializing a UDF with dill.dumps(udf, recurse=True), as Transformation.to_proto() and StreamFeatureView.to_proto() do, fails as soon as the UDF refers to a module-level global, such as pd in a pandas UDF:

TypeError: _Pickler._batch_setitems() missing 1 required positional argument: 'obj'

So an on-demand feature view written like the docs example can't be applied on 3.14:

@on_demand_feature_view(
    sources=[driver_stats, request],
    schema=[Field(name="conv_rate_plus_val", dtype=Float64)],
    mode="pandas",
)
def transformed_conv_rate(inputs: pd.DataFrame) -> pd.DataFrame:
    df = pd.DataFrame()
    df["conv_rate_plus_val"] = inputs["conv_rate"] + inputs["val_to_add"]
    return df

transformed_conv_rate.to_proto()  # TypeError on Python 3.14 with dill 0.3.9

dill added Python 3.14 support in 0.4.0 and made it formal in 0.4.1. This widens the requirement to dill>=0.3.0,<0.5 and records it in pixi.lock (regenerated with pixi lock; the locked dill stays at 0.3.9). The sdk/python/requirements lock files are unchanged and still resolve dill 0.3.9 for 3.10–3.12, so CI keeps testing the same versions; installs on 3.14 now get a dill that works.

A UDF serialized with dill 0.3.9 loads with 0.4.1 and the other way round (checked on 3.12), so existing registries and mixed client/server versions keep working.

Misc

CI runs Python 3.10–3.12, which is why this doesn't show up there, and I didn't add a test for the same reason: the existing on-demand feature view tests cover it on 3.14. Locally, on macOS:

Python 3.14.7 with -e ".[test,k8s,aws,gcp]": the ODFV, transformation and stream feature view unit tests (103 tests in 11 files) have 15 failures with the TypeError above on dill 0.3.9, and none on dill 0.4.1. Five further tests need pyspark, which I didn't install, and fail either way.
Python 3.12 with sdk/python/requirements/py3.12-ci-requirements.txt: the full sdk/python/tests/unit run gives 2773 passed, 44 skipped with dill 0.3.9, and the same with dill 0.4.1 swapped in.

@YHC66 Please run make lock-python-dependencies-all to update requirements file

YHC66 · 2026-09-25T15:48:06Z

Done: rebased on current master and regenerated all the lock files with the lock-python-dependencies-all recipe (ab57414); every requirements file now pins dill==0.4.1. One thing I hit while running it: pybuild-deps==0.5.0 fails at the output step with the newly released pip-tools 7.6.1 (OutputWriter.__init__() got an unexpected keyword argument 'generate_hashes'), so I ran the build-deps step with pip-tools 7.5.3. You may want to pin that in the Makefile at some point.

* fix(operator): Set grpc appProtocol on the offline Service port The offline server is an Arrow Flight (gRPC) server, but its Service port was rendered with name "http" and no appProtocol. Protocol-aware meshes such as Istio then fall back to HTTP/1.1 and break gRPC traffic. Extend getServiceAppProtocol() to return "grpc" for OfflineFeastType, following the same pattern used for the registry gRPC Service. Signed-off-by: Chaitany Patel <patelchaitany93@gmail.com> * fix: Infer the tensor type from retrieved values in to_tensor to_tensor decides between a torch.Tensor and a plain list by looking at the first value that is not None, but it searches the list where the missing values have already been replaced by default_value. That default is float('nan') by default, which is not None, so the search always returns the first element. When the first entity row is missing, the type is then read off the default rather than off the feature. A string feature whose first row is absent, the ordinary case of an entity key that is not in the online store, raises 'Failed to convert values for ... to tensor: new(): invalid data type' instead of returning the list the docstring promises. Reordering the entity rows makes the error disappear. Read the first present value from the retrieved list. The fallback stays default_value so that a fully missing numeric feature keeps taking the tensor path, which the added regression test pins. Signed-off-by: Rodrigo-Palma <email.rodrigopalma@gmail.com> * fix: Authorize registry server writes before deserializing UDFs ApplyValidationReference and ApplyMaterialization built the full domain object inside the argument list of their permission check: assert_permissions( resource=FeatureView.from_proto(request.feature_view), actions=[AuthzedAction.WRITE_ONLINE], ) Python evaluates arguments first, so from_proto() — which dill-loads the caller-supplied UDF — always ran before assert_permissions() could reject the request. Unpickling executes arbitrary code, so an unauthorized caller achieved code execution and only then received a permission error. Load metadata first, authorize, and deserialize only after the check passes. The permission check needs just name/project/tags, never the callable itself. FeatureView.from_proto() already accepted skip_udf; this adds the same parameter to ValidationReference.from_proto(), gating both the GEProfiler and GEProfile dill payloads. As a result profiler may now legitimately be unset, so it becomes Optional and the profile property raises a clear error rather than failing on None. This covers the registry server paths only. Deserialization on the feature server is not addressed here. Signed-off-by: Chaitany Patel <patelchaitany93@gmail.com> * docs: Fix auth type in rbac-remote example and typos in docs The rbac-remote README told readers to set the client auth type to `kuberentes`, while the linked feature_store.yaml (and Feast itself) uses `kubernetes`. Copying the documented value gives an invalid auth type. Also corrects spelling in the docs: directories, entity, versions, every time, workflow, Registries, accommodate, supersede, running, activities, and a doubled "the the".

That difference is load bearing. aggregation_specs_to_agg_ops rejects a windowed aggregation in online serving with 'if getattr(agg, "time_window", None) is not None', so an on demand feature view with a plain Aggregation(column=..., function=...) works in process and then fails with 'Time window aggregation is not supported in online serving.' on the first get_online_features after feast apply, whatever the registry. The same round-trip runs for StreamFeatureView. Read the field through HasField, which is available because both are google.protobuf.Duration message fields. Aggregation.__eq__ compares these two attributes, so this also stops a registry diff from seeing an unchanged feature view as modified.
