This PR addresses three related GraphRAG reliability issues that
together allow long-running GraphRAG tasks (10+ hours of LLM extraction)
to be resumed after a crash or pause without re-doing completed work. It
builds on #14096 (per-doc subgraph cache) and extends the same idea to
the resolution and community-detection phases.
Fixes#14236.
## 1. Fix concurrent merge crash
Long GraphRAG runs would crash near the end of entity resolution with:
```
RuntimeError: dictionary keys changed during iteration
```
in `Extractor._merge_graph_nodes`. Two changes:
- `rag/graphrag/general/extractor.py`: snapshot `graph.neighbors(node1)`
via `list(...)` before iterating, so concurrent `add_edge` /
`remove_node` mutations on the shared `nx.Graph` cannot invalidate the
iterator. Also tracks each redirected neighbour in `node0_neighbors` so
a later merged node sharing the same external neighbour takes the
edge-merge branch instead of overwriting via `add_edge`.
- `rag/graphrag/entity_resolution.py`: serialize the merge step with a
dedicated `asyncio.Semaphore(1)`. `nx.Graph` is not thread-safe and
concurrent merges on overlapping neighbourhoods can produce incorrect
results even with the snapshot fix.
## 2. Don't wipe partial graph on pause
Previously the pause / cancel UI path called
`settings.docStoreConn.delete({"knowledge_graph_kwd": [...]}, ...)`,
destroying every subgraph, entity, relation, and graph row.
Re-triggering then started GraphRAG from scratch even though #14096 had
already added `load_subgraph_from_store`.
After main was merged in (which deleted `api/apps/kb_app.py` per
#14394), the pause path now lives on the new REST surface `DELETE
/v1/datasets/<id>/<index_type>`:
- `api/apps/services/dataset_api_service.py`: `delete_index` accepts a
`wipe: bool = True` parameter. When `False` the doc-store rows and
GraphRAG phase markers are left intact and only the running task is
cancelled. Default preserves historical behaviour.
- `api/apps/restful_apis/dataset_api.py`: parses `?wipe=false|0|no|off`
from the query string and forwards it.
- `web/src/utils/api.ts` + `web/src/services/knowledge-service.ts`:
`unbindPipelineTask` appends `?wipe=false` when explicitly false.
- The GraphRAG pause action in
`web/src/pages/dataset/dataset/generate-button/hook.ts` passes `wipe:
false` for `KnowledgeGraph`; raptor is unchanged.
**UX impact:** the pause icon next to a running GraphRAG task no longer
wipes graph data. The only path that still wipes is the explicit Delete
action in `GenerateLogButton` (trash icon behind a confirmation modal).
## 3. Phase-completion markers (`rag/graphrag/phase_markers.py`)
A small Redis-backed marker layer at
`graphrag:phase:{kb_id}:{resolution_done|community_done}` (7-day TTL).
`run_graphrag_for_kb` consults the markers on entry and skips phases
that already completed in a prior run. Markers are cleared automatically
when:
- new docs are merged into the graph (which invalidates prior resolution
and community results),
- `delete_index` wipes the graph, or
- `delete_knowledge_graph` is called.
Redis failures never block a run -- markers are an optimization, not a
gate.
## 4. Idempotent community detection
`extract_community` previously did `delete-then-insert` on
`community_report` rows; a crash mid-insert left the dataset with no
reports. Now report IDs are derived deterministically from `(kb_id,
community.title)`, the existing report IDs are snapshotted before
insert, new rows are written, then only stale rows are pruned. A failure
at any step leaves either the prior or the new report set intact --
never a partial mix.
## 5. Tunable doc-store insert pipeline
The GraphRAG insert loop in `rag/graphrag/utils.py` and the
`community_report` insert in `rag/graphrag/general/index.py` were both
hardcoded to `es_bulk_size = 4` and ran strictly sequentially. On a real
KB this meant 1077 chunks took ~21 minutes for a 100-chunk slice -- pure
round-trip overhead.
- New `insert_chunks_bounded()` helper in `rag/graphrag/utils.py`
batches inserts via a bounded `asyncio.Semaphore`. Same retry / timeout
semantics as the prior loop.
- Defaults: 64 docs per batch, 4 batches in flight (matches the regular
ingest pipeline in `document_service.py`). Tunable per-deployment via
`GRAPHRAG_INSERT_BULK_SIZE` and `GRAPHRAG_INSERT_CONCURRENCY`.
- Both `set_graph` and `extract_community` now use the helper.
This dropped the same 1077-chunk insert from minutes to seconds in local
testing without measurable extra pressure on Infinity (total in-flight
docs ≤ `BULK_SIZE × CONCURRENCY` = 256 by default).
## Tests
- `test/unit_test/rag/graphrag/test_merge_graph_nodes.py` (3 tests):
dense neighbourhood merge, neighbour-snapshot regression, concurrent
serialized merges.
- `test/unit_test/rag/graphrag/test_phase_markers.py` (4 tests): set/has
round-trip, kb-scoped clear, no-op on empty input, graceful Redis
failure.
-
`test/testcases/test_web_api/test_dataset_management/test_dataset_sdk_routes_unit.py`:
new `test_delete_index_wipe_flag_unit` covers `wipe=false` for both
GraphRAG and raptor on the new REST route, and confirms the default
still wipes and clears phase markers.
## Compatibility
- Backward compatible: tasks queued before this change behave
identically (default `wipe=true`, no markers expected).
- No schema/migration changes; all new state lives in Redis.
- New optional REST query param `wipe` on `DELETE
/v1/datasets/<id>/<index_type>`.
- New optional env vars `GRAPHRAG_INSERT_BULK_SIZE` and
`GRAPHRAG_INSERT_CONCURRENCY`; defaults preserve safe behaviour.
## Example of resume

applying the concurrency fix and re-deploying.

### What problem does this PR solve?
This PR fixes missing authorization checks in the Memory API.
Previously, several authenticated endpoints accepted caller-supplied
`tenant_id`, `owner_ids`, or `memory_id` values and used them directly
to list, read, update, delete, or search Memory data.
That could allow an authenticated user to access or mutate another
tenant's Memory records if they knew a tenant ID or memory ID. The fix
centralizes Memory access checks and applies them consistently across
Memory and Memory-message operations.
The change:
- Adds helper logic to parse list filters and compute tenant IDs
accessible to `current_user`.
- Requires direct `memory_id` operations to pass Memory access checks
before reading, updating, deleting, or changing message state.
- Filters list/search/recent-message requests to accessible memories
only.
- Applies Memory visibility filtering before count and pagination in
`MemoryService.get_by_filter`.
- Accepts `owner_ids` in the Memory list route, matching the frontend
owner filter while still intersecting values with the caller's
accessible tenants.

### What problem does this PR solve?
## Summary
Fixed a bug where the **File Logs** tab in the dataset ingestion page
always showed "No logs" even after files were parsed successfully.
## Root Cause
Both the **File Logs** and **Dataset Logs** tabs on the frontend called
the same backend endpoint `/datasets/{dataset_id}/ingestions`. However,
the backend only queried `get_dataset_logs_by_kb_id`, which
hard-filtered records by `document_id == GRAPH_RAPTOR_FAKE_DOC_ID`
(dataset-level logs). As a result, real file-level logs were never
returned, causing the table to appear empty.
## Changes
### Backend
- **`api/apps/restful_apis/dataset_api.py`**
- Added two new query parameters to `list_ingestion_logs`:
- `log_type` — `"file"` or `"dataset"` (default: `"dataset"`)
- `keywords` — search keyword for filtering by document / task name
- **`api/apps/services/dataset_api_service.py`**
- Updated `list_ingestion_logs` signature to accept `log_type` and
`keywords`.
- Added conditional routing:
- When `log_type == "file"`, call
`PipelineOperationLogService.get_file_logs_by_kb_id`
- Otherwise, call
`PipelineOperationLogService.get_dataset_logs_by_kb_id`
- **`api/db/services/pipeline_operation_log_service.py`**
- Extended `get_dataset_logs_by_kb_id` with an optional `keywords`
parameter so dataset logs can also be searched.
### Frontend
- **`web/src/pages/dataset/dataset-overview/hook.ts`**
- Removed the separate API function switching (`listPipelineDatasetLogs`
vs `listDataPipelineLogDocument`).
- Unified both tabs to call `listDataPipelineLogDocument` with the new
`log_type` query parameter (`"file"` or `"dataset"`).
- Ensured `keywords` and filter values are passed through correctly.
## Behavior After Fix
| Tab | `log_type` | Returned Records | Searchable Field |
|---|---|---|---|
| File Logs | `file` | Real document-level logs | `document_name` (file
name) |
| Dataset Logs | `dataset` | GraphRAG / RAPTOR / MindMap logs |
`document_name` (task type) |

### What problem does this PR solve?
Closes#13857
Parent-child chunking was introduced in v0.23.0 but is only configurable
through the web UI. Users managing datasets programmatically cannot
enable it via the HTTP API or Python SDK because `ParserConfig` uses
`extra="forbid"`, rejecting the `children_delimiter` field at
validation.
### What does this PR change?
Adds a `parent_child` nested config to `ParserConfig`, following the
same pattern as `raptor` and `graphrag`:
```json
"parser_config": {
"parent_child": {
"use_parent_child": true,
"children_delimiter": "\n"
}
}
```
- api/utils/validation_utils.py — new ParentChildConfig model, added to
ParserConfig
- api/utils/api_utils.py — naive defaults + flatten to
children_delimiter for the execution layer
- api/apps/services/dataset_api_service.py — flatten on the update path
- test/testcases/configs.py — updated DEFAULT_PARSER_CONFIG
-
test/testcases/test_http_api/test_dataset_management/test_create_dataset.py
— 4 valid + 2 invalid test cases
No changes to the execution layer (rag/app/naive.py, rag/nlp/search.py).
Existing UI flow via ext is unaffected.
