feat: Adds registry REST API endpoints for managing entities, data sources, and feature views by rohit-bharmal · Pull Request #6413 · feast-dev/feast

rohit-bharmal · 2026-05-18T06:20:29Z

What this PR does / why we need it:

Adds REST API endpoints for managing entities, data sources, and feature views
via the registry server. These endpoints are part of the control plane API,
enabling create/apply and delete operations over HTTP without needing a direct
gRPC connection.

Endpoints added:

GET/POST/DELETE /entities — list, apply, and delete entities
GET/POST/DELETE /data-sources — list, apply, and delete data sources
GET/POST/DELETE /feature-views — list, apply, and delete feature views

Replaces earlier proto-based approach with a clean REST layer backed by the
existing gRPC registry handler.

Which issue(s) this PR fixes:

Fixes #6192

+                grpc_call(grpc_handler.GetDataSource, ds_req)
+                batch_source_proto = DataSourceProto(name=body.batch_source)
+            except Exception:
+                batch_source_proto = DataSourceProto(name=body.batch_source)


I see both try and except block has same code, couldn't simply batch_source_proto = DataSourceProto(name=body.batch_source) will work ?

Yeah Right! Removed the code and kept it simple and also added Unit tests

@rohit-bharmal Please also include unit tests

@ntkathole I am not sure why the tests are failing. Do you have any idea about this?

ntkathole · 2026-05-18T12:22:46Z

+    def apply_data_source(body: ApplyDataSourceRequestBody):
+        ds_proto = DataSourceProto(
+            name=body.name,
+            type=body.type or 1,  # type: ignore[arg-type]


I think we should not send explicit values if it's not available, it may change behavior

Yeah right! I removed the explicit value and made changes accordingly.

ntkathole · 2026-05-18T12:25:39Z

+            DataSourceProto(name=body.batch_source) if body.batch_source else None
+        )
+
+        ttl = Duration(seconds=body.ttl_seconds) if body.ttl_seconds else None


same as above false value may get passed. If user sends "ttl_seconds": 0 (features never expire), which is valid ttl value, it will be silently dropped.

Yeah right! I removed the explicit value and made changes accordingly.
