The Stored Files modal and per-file warnings panel both enumerate
distinct 'source' values in the qdrant content collection. The
existing implementation scrolls every point in the collection, 100 per
page, just to learn the unique sources. On a fully-ingested NOMAD this
is brutally slow: NOMAD3's 3.1M-point collection takes 50+ seconds to
return its ~40 distinct sources, and the same scan runs twice per modal
open (getStoredFiles + computeFileWarnings each pay it independently).
Qdrant 1.10+ supports a facet aggregation that returns the distinct
values of a payload field with their counts in a single call.
@qdrant/js-client-rest@1.16.2 (already pinned) exposes this as
`client.facet()`. Swap the three scroll loops:
- RagService.getStoredFiles
- RagService.computeFileWarnings
- RagService.\_scanAndSync (the source-set used for skip-already-embedded
decisions)
As a bonus, computeFileWarnings's per-source chunk count comes back
inline from the facet, so the secondary scroll that was incrementing a
counter is also gone.
`exact: true` everywhere because the counts feed Warning A's
zero_chunks decision and could mis-fire near thresholds otherwise. New
RagService.FACET_SOURCE_LIMIT = 10000 caps the facet response; real
NOMADs run ~100 sources max, this is comfortable headroom.
Expected impact on NOMAD3 (3M points, 40 sources): ~50s -> ~100ms per
endpoint. On an empty/fresh KB: no measurable change either way.
