fix: Encode non-finite floats in feature server JSON responses by Zhuoxi2000 · Pull Request #6930 · feast-dev/feast

Zhuoxi2000 · 2026-10-02T11:23:14Z

What this PR does / why we need it:

A stored NaN or +/-inf float value makes POST /get-online-features fail with HTTP 500 (ValueError: Out of range float values are not JSON compliant). _value_to_native returns raw Python floats, and JSONResponse serializes with allow_nan=False, so one non-finite value fails the whole multi-feature response. The SDK get_online_features().to_dict() path serves the same value fine. /search and /retrieve-online-documents share convert_response_to_dict and are affected too.

This PR encodes non-finite values as the protobuf JSON mapping strings "NaN", "Infinity" and "-Infinity". This applies to:

scalar double_val / float_val
double_list_val, float_list_val, double_set_val, float_set_val (element-wise)

Finite values are unchanged, and lists without non-finite values still go through a plain list(...). Nested list_val / map_val / struct_val values get the fix through the existing recursion. The convert_response_to_dict docstring documents the encoding.

If maintainers would rather emit null for non-finite values (the behaviour while ORJSONResponse was in use), this is a one-line change in _float_to_native.

Not covered here: RemoteOnlineStore._build_online_response_from_json infers value types from the JSON, so it would read the encoded strings as strings and rejects a list that mixes numbers and strings. This path already failed before (the server returned 500), and null would not round-trip through it either. I can follow up on the client side once the encoding is settled.

Which issue(s) this PR fixes:

No separate issue; the bug is described above.

Testing is not required for this change

New tests:

tests/unit/test_feature_server.py::test_get_online_features_serves_non_finite_float[inf|-inf]: writes +/-inf to the online store, checks that the SDK serves it, then checks that /get-online-features returns 200 with "Infinity" / "-Infinity" and status PRESENT.
tests/unit/test_feature_server_utils.py: covers NaN/inf/-inf for double_val and float_val, the four float/double list and set types, and a json.dumps(..., allow_nan=False) round trip of convert_response_to_dict.

From sdk/python:

python -m pytest tests/unit/test_feature_server_utils.py tests/unit/test_feature_server.py -q

Without the fix (the tests only): 13 failed, 97 passed. Every new test fails, and the endpoint test fails with assert 500 == 200 / Out of range float values are not JSON compliant.
With the fix: 110 passed.

tests/unit/test_proto_json.py, tests/unit/test_feature_server_async.py and tests/unit/infra/feature_servers/test_mcp_server.py also pass (28 passed). ruff check and ruff format --check (0.16.9) are clean on the changed files.

The one failing job, unit-test-python (3.11, macos-14), errored during the setup of test_push_and_get. The feast apply subprocess in cli_repo_creator.local_repo timed out twice ("Command timed out after 120s (attempt 2/2): ['apply']"). That step isn't touched by this change.

The other four unit-test jobs passed, including macos-14 on 3.12. In that job, 2985 tests passed with 1 setup error. Could someone re-run it when convenient?

When a collection contains a non-finite value, this checks elements until the first such value and then traverses the collection again to build the converted list. For large feature vectors with a late non-finite value, that adds avoidable work. Consider materializing the values once and checking/converting that list.

Suggested:

Thanks @jyejare, good catch.

Materialize the values once (96a7d62)

The float/double list and set branch now copies the repeated field into a list once, runs all(map(math.isfinite, vals)) on that list, and returns it as is when every value is finite. The conversion only runs when a non-finite value is present, and it reads the same plain list, so the protobuf container is iterated only once.

On 1,000 doubles, this brings the all-finite case from 28 to 18 µs and the "last value is NaN" case from 49 to 42 µs. I kept the C-level all() check instead of a single per-element Python loop. That loop is a true single pass and measured about 23 to 25 µs whatever the input, so it would make the common all-finite path slower (from 18 to about 24 µs) while making the non-finite path faster (from 42 to about 24 µs). If you'd rather favour the non-finite case, I can switch to it.

Other changes

dfc7200 restores the CRLF line endings of sdk/python/tests/unit/test_feature_server.py. My first commit had converted the file to LF, so the diff showed the whole file as rewritten. It now shows only the 53 added lines.
e1c6870 merges the latest master. There were no conflicts.

Tests and checks

$ python -m pytest tests/unit/test_feature_server_utils.py tests/unit/test_feature_server.py -q
110 passed

With feature_server_utils.py reverted to master, the same run gives 13 failed and 97 passed, and every failure is one of the new tests. test_proto_json.py, test_feature_server_async.py and infra/feature_servers/test_mcp_server.py pass (28 passed). ruff check and ruff format --check (0.16.9) pass on sdk/python/feast/ and sdk/python/tests/, and mypy 1.11.2 reports no issues in feature_server_utils.py.

A stored NaN or +/-inf float made /get-online-features (and the other endpoints that use convert_response_to_dict) fail with HTTP 500, because JSONResponse serializes with allow_nan=False. Encode non-finite values in float/double scalars, lists and sets as the protobuf JSON strings "NaN", "Infinity" and "-Infinity". Signed-off-by: Edson <zhuoxi2000@gmail.com>

Copy the repeated field into a list once and run the finite check and the conversion on that list, instead of iterating the protobuf container for the check and again for the conversion. Signed-off-by: Edson <zhuoxi2000@gmail.com>
