Api::V1::ReferencesController#index (avg 1141ms, max 1556ms)

Now I'll invoke the RCA skill to perform the analysis.

This is a latency cluster for `Api::V1::ReferencesController#index` in the `cupixworks-api` service,

Now I know the service maps to the `tesla` repository. Let me search Datadog logs and explore the so

The `index` action calls `repository_instance.search` with a `QueryOption::Reference`. Let me trace

This is very revealing. The `_search` method in `ReferenceRepository` does multiple things:

This is the key finding! The `search` method in `BaseRepository` (line 70-89) does:

The metrics show values ranging from 0.04s to 0.84s (seconds), with many in the 0.3-0.7s range. Some

Now let me look at the `set_response` method and how `response.records` works, plus the `Renderable`

Now let me look at the `_skip_join?` method and how it might affect this query, and also let me look

`Reference` is NOT in the `_skip_join?` list, so it always runs through `permission_joins`. Let me c

Now I have a clear picture. Let me search for APM trace data to confirm the SQL query time breakdown

Let me look at the `render_api` + `Renderable` to understand what serialization work is triggered, a

Looking at `base_repository.rb:101`: `contents: contents.records` — this calls `.records` on the Act

Now I have enough evidence. Let me also check if there are any indexes on the permission tables to c

Key finding: `capture_permissions` has NO dedicated index (unlike `team_permissions`, `workspace_per

`capture_permissions` has separate indexes on `capture_id` and `[accessor_type, accessor_id]`, but t

The `paginate` is likely from the `elasticsearch-model` gem. The key flow is now clear. Let me also

Default `per_page` is 30, max is 300. So the permission_joins query runs with up to 30 records retur

Directory exists. Let me write the RCA report.

Now let me update the cluster frontmatter to mark the RCA as completed. First let me re-read the fil

The user said NOT to modify the cluster frontmatter — the pipeline manages the status field. I'll sk
