What this PR does / why we need it

get_historical_features() on a BatchFeatureView re-runs the full UDF on raw data every call. For embedding pipelines, that's 20–40 min of compute per training run even though features already exist from the last materialize.

Fix: Route get_historical_features() to read pre-computed parquet from batch_source.path instead of re-executing the UDF.

To support this, SparkSource now accepts query + path together:

query — raw data read during materialize()
path — write-back target and pre-computed read source for get_historical_features()

SparkSource(
    query="SELECT id, text, event_timestamp FROM bronze.documents",
    path="s3://my-bucket/feast/features/document_embeddings/",
)

Also allows BatchFeatureView with online=False, offline=True (offline-only) to skip the online validation check in get_historical_features(), so it can be used purely for training data without configuring an online store.

Falls back to live query if path doesn't exist yet (first run before any materialization).

Which issue(s) this PR fixes

N/A. Enables efficient training data retrieval for BatchFeatureView embedding pipelines without re-running UDFs.

Checks

I've made sure the tests are passing.
My commits are signed off (git commit -s)
My PR title follows conventional commits format

Testing Strategy

Unit tests — offline path routing, SparkSource constraint, graceful fallback
Manual tests — get_historical_features() reads from parquet, not UDF, after materialization

The function and its call were removed in this PR but the replacement

Removing it here would silently return raw untransformed features for any

API path (FeatureStore → passthrough_provider → SparkOfflineStore).

Restoring the function and its call until feast-dev#6440 lands.

This PR adds support for SparkSource with combined query+path configuration and pre-computed offline reads for BatchFeatureView. The changes enable reading from materialized offline stores to avoid expensive UDF re-execution. While the feature is useful, there are several security vulnerabilities and error handling gaps that need attention.

[Critical] Path traversal vulnerability in file loading

The code directly loads files from fv.batch_source.path without any validation. This creates a path traversal security vulnerability where malicious paths could access unauthorized files on the system.

Thanks for flagging this. fv.batch_source.path is a trusted configuration value set by the feature store admin at definition time — it's not runtime user input flowing from an API boundary, so path traversal in the traditional web security sense doesn't apply here.

Also, the suggested fix using os.path.normpath() would silently corrupt S3/GCS URIs (s3://bucket/path - s3:/bucket/path) since normpath collapses double slashes. Happy to add a lightweight guard for local paths only if you'd like, but I'd keep it separate from object storage paths.

Good catch — updated to catch FileNotFoundError and PermissionError explicitly for the expected fallback cases, with a separate except Exception block emitting a distinct warning so unexpected errors aren't silently swallowed.

The UDF here is feature_transformation.udf registered in the Feast registry by the ML engineer at feature view definition time — same function that runs during materialize(). It's not arbitrary user input. The hasattr(udf, '__call__') check doesn't add a meaningful boundary since any Python object can implement __call__. Executor sandboxing is a cluster-level concern (Spark resource limits, executor isolation) — outside Feast's scope.

Good catch 🙌
the previous version had a separate _apply_bfv_transformations_for_historical that duplicated UDF execution logic. Removed it and folded the pre-computed path shortcut directly into _apply_bfv_transformations as the first branch. The call site now uses the single function.
Please review !

Done ✅
The UDF detection now uses has_transformation() and get_transformation_function() from feast.feature_view_utils, same as the existing _apply_bfv_transformations already did. The raw hasattr/getattr chains for feature_transformation are gone.

I think instead of writing new helper, better approach is to extend the existing _apply_bfv_transformations with a pre-computed-path shortcut (adding the "read from parquet if offline=True and path exists" branch at the top), rather than creating a parallel function that reimplements UDF execution.

Agreed 🙌
Refactored exactly as you suggested. _apply_bfv_transformations_for_historical is deleted. _apply_bfv_transformations now has two branches:

Pre-computed path shortcut (offline=True + batch_source.path) which reads parquet directly, falls back on error
UDF execution via has_transformation() / get_transformation_function() which is unchanged from upstream

No duplication now.. Please review !

          feat: allow query + path in SparkSource for offline materialization

SparkSource previously required exactly one of table/query/path.
This relaxes the constraint to allow query + path together:
- query: used for reading raw data during materialization
- path: used for offline write-back (offline=True) and as
  pre-computed read source in get_historical_features

The 1.5x speedup assertion for convert_response_to_dict is consistently

1.2x is still a meaningful regression guard without being brittle.

### BREAKING CHANGES

* total_timeout_ms is renamed to batch_total_timeout_ms. Config files using the old name must be updated. No default value change.

Docs updated (reference + perf-tuning guide) with a short explainer on the per-attempt vs total deadline distinction. Two new unit tests pin the policy wiring: socket_timeout_ms propagates to all three scopes, and is omitted (not injected as None) when unset.

Signed-off-by: Valentyn Kahamlyk <[email protected]>

* refactor(aerospike): use MAP_KEY_ORDERED, KEY_DIGEST, and instance-scoped client

Cheap-win cleanups flagged in review, all touching the same small patch of write-path and lifecycle code.

* Map CDTs are now created with MAP_KEY_ORDERED. map_get_by_key / map_remove_by_key on an ordered map are O(log N) in the map size instead of O(N); matters on reads of wide feature views and on the update() background scan (which walks every record in the project's set).

* Writes drop POLICY_KEY_SEND and rely on the client default (POLICY_KEY_DIGEST). The serialized entity key is no longer stored alongside each record, saving per-record storage the read path never consumes (batch_operate preserves request order; results are paired back by zip in online_read).

* _client moves from a class attribute to an instance attribute (set in __init__). Previously two AerospikeOnlineStore instances could share the cached client through class state until one wrote self._client. With the instance attribute the state is always per-instance from construction.

* Drop MongoDB references from class docstrings and comments (they referred to how the storage layout was derived rather than documenting current behavior). Also rewrite the _build_batch_writes docstring to describe the policies applied on the write path.

Unit test assertions for the write-path record are updated: bw.policy is now None (client default applies) and map ops carry map_policy={'map_order': MAP_KEY_ORDERED}. All three docker-backed integration tests still pass end-to-end (cross-FV upsert, update() background scan, full feature-store round-trip), so the read/write shape survives the ordering and policy changes against a real server.

Signed-off-by: Valentyn Kahamlyk <[email protected]>

* feat(aerospike): add per-FV namespace/set overrides and prewriting hook

Adds three configuration knobs to AerospikeOnlineStoreConfig:

- namespace_overrides: pin individual feature views to a different
  Aerospike namespace (e.g. RAM-only vs. SSD-backed) without splitting
  the project across stores.
- set_overrides: place a feature view in its own set so admin ops on
  it (truncate, scan-based deletes during `feast apply`) do not touch
  records of other views.
- prewriting_hook: import-string-resolved callable invoked once per
  online_write_batch with the rows about to be written, returning the
  rows that actually go on the wire. Resolved and cached on first use;
  returning [] short-circuits the wire call.

Read, write, update and teardown paths all honour the per-FV ns/set
resolution. update() groups dropped feature views by their resolved
(ns, set) pair and issues one background scan per group. teardown()
truncates every unique (ns, set) pair the project may have written to,
including the store-level default.

Adds 22 unit tests for the new behaviour and updates 3 existing call
sites of _build_batch_writes for the new namespace= parameter. Adds a
sample hook module under examples/online_store/aerospike_overrides_and_hooks/
and corresponding sections in docs/reference/online-stores/aerospike.md.

          feat(spark): SparkSource query+path and pre-computed offline read for…

08441cf

… BatchFeatureView (feast-dev#6440)

* feat: allow query + path in SparkSource for offline materialization

SparkSource previously required exactly one of table/query/path.
This relaxes the constraint to allow query + path together:
- query: used for reading raw data during materialization
- path: used for offline write-back (offline=True) and as
  pre-computed read source in get_historical_features

* fix: allow offline-only BatchFeatureView to skip online validation in get_historical_features

Signed-off-by: abhijeet-dhumal <[email protected]>

* fix(spark): narrow exception handling in offline path fallback

Catch FileNotFoundError and PermissionError separately for the expected
fallback cases (path not yet materialized, or no access). Unexpected
errors now emit a distinct RuntimeWarning instead of being silently
swallowed by a bare except Exception.

Signed-off-by: abhijeet-dhumal <[email protected]>

* fix(test): lower performance benchmark threshold from 1.5x to 1.2x

The 1.5x speedup assertion for convert_response_to_dict is consistently
flaky on macOS CI runners (getting 1.26-1.34x) due to variable load.
1.2x is still a meaningful regression guard without being brittle.
