fix: Key registry proto caches on the proto, not its id() by jiwidi · Pull Request #7085 · feast-dev/feast

jiwidi · 2026-10-28T11:05:16Z

What this PR does / why we need it:

proto_registry_utils caches its results by id(registry_proto) and version_id. SqlRegistry
leaves version_id empty. After a registry proto is freed, a new proto can get the same id(),
and the cache then returns objects from the old registry. In our case write_to_online_store
validated a vector against a feature view from an earlier FeatureStore and rejected valid rows.

The caches now keep a reference to the proto and compare it by identity. The version_id and
project keys are unchanged.

Testing is not required for this change
Unit: two live registry protos that share one id() (patched in the module) each get their own
value from all three cache decorators. The test fails on the old code on every run.

The existing registry cache tests pass unchanged.

Misc

Found while running a streaming writer against the Milvus online store; independent of the Milvus
online store PRs.

The proto_registry_utils caches keyed on id(registry_proto) and version_id. SqlRegistry leaves version_id empty. After a registry proto is freed, a new proto can get the same id, and the cache then returns objects from the old registry. For example, write_to_online_store validated a vector against a feature view from an earlier store and rejected valid rows. The caches now keep the proto and compare it by identity.

LGTM.
Non-blocking: Make the ID-reuse regression test deterministic and cover all three cache decorators.

The test depended on CPython giving the second proto the freed address of the first. It now patches id() in the module so both live protos share one id, and it covers all three cache decorators. Signed-off-by: jiwidi <[email protected]>

LGTM. Non-blocking: Make the ID-reuse regression test deterministic and cover all three cache decorators.

Thanks! Pushed a new commit for itt. The test now patches id on the module so both protos share one id while both are alive, no more relying on the allocator reusing the address, and it is parametrized over the three decorators (list_project_metadata, list_entities, get_any_feature_view). Checked it fails on every run against the old code.
