      - Monitoring tasks (every 5 minutes)
      - Cleanup tasks (hourly)
 
+#### Worker Deployment Modes
+
+Onyx supports two deployment modes for background workers, controlled by the `USE_LIGHTWEIGHT_BACKGROUND_WORKER` environment variable:
+
+**Lightweight Mode** (default, `USE_LIGHTWEIGHT_BACKGROUND_WORKER=true`):
+
+- Runs a single consolidated `background` worker that handles all background tasks:
+  - Light worker tasks (Vespa operations, permissions sync, deletion)
+  - Document processing (indexing pipeline)
+  - Document fetching (connector data retrieval)
+  - Pruning operations (from `heavy` worker)
+  - Knowledge graph processing (from `kg_processing` worker)
+  - Monitoring tasks (from `monitoring` worker)
+  - User file processing (from `user_file_processing` worker)
+- Lower resource footprint (fewer worker processes)
+- Suitable for smaller deployments or development environments
+- Default concurrency: 20 threads (increased to handle combined workload)
+
+**Standard Mode** (`USE_LIGHTWEIGHT_BACKGROUND_WORKER=false`):
+
+- Runs separate specialized workers as documented above (light, docprocessing, docfetching, heavy, kg_processing, monitoring, user_file_processing)
+- Better isolation and scalability
+- Can scale individual workers independently based on workload
+- Suitable for production deployments with higher load
+
+The deployment mode affects:
+
+- **Backend**: Worker processes spawned by supervisord or dev scripts
+- **Helm**: Which Kubernetes deployments are created
+- **Dev Environment**: Which workers `dev_run_background_jobs.py` spawns
+
 #### Key Features
 
 - **Thread-based Workers**: All workers use thread pools (not processes) for stability

 Before writing your plan, make sure to do research. Explore the relevant sections in the codebase.
 
-## Error Handling
-
-**Always raise `OnyxError` from `onyx.error_handling.exceptions` instead of `HTTPException`.
-Never hardcode status codes or use `starlette.status` / `fastapi.status` constants directly.**
-
-A global FastAPI exception handler converts `OnyxError` into a JSON response with the standard
-`{"error_code": "...", "message": "..."}` shape. This eliminates boilerplate and keeps error
-handling consistent across the entire backend.
-
-```python
-from onyx.error_handling.error_codes import OnyxErrorCode
-from onyx.error_handling.exceptions import OnyxError
-
-# ✅ Good
-raise OnyxError(OnyxErrorCode.NOT_FOUND, "Session not found")
-
-# ✅ Good — no extra message needed
-raise OnyxError(OnyxErrorCode.UNAUTHENTICATED)
-
-# ✅ Good — upstream service with dynamic status code
-raise OnyxError(OnyxErrorCode.BAD_GATEWAY, detail, status_code_override=upstream_status)
-
-# ❌ Bad — using HTTPException directly
-raise HTTPException(status_code=404, detail="Session not found")
-
-# ❌ Bad — starlette constant
-raise HTTPException(status_code=status.HTTP_403_FORBIDDEN, detail="Access denied")
-```
-
-Available error codes are defined in `backend/onyx/error_handling/error_codes.py`. If a new error
-category is needed, add it there first — do not invent ad-hoc codes.
-
-**Upstream service errors:** When forwarding errors from an upstream service where the HTTP
-status code is dynamic (comes from the upstream response), use `status_code_override`:
-
