qdrant introduces risk embedding

Source: Technology·Target: Failure Mode

Summary

Qdrant stores pre-computed embeddings that become stale when source document content changes or when the embedding model version is updated, requiring scheduled re-embedding and index rebuild.

Evidence

·qdrant lists embedding drift as a failure mode and notes migrating models requires full re-embedding and reindex (technologies/qdrant.yaml)
·embedding_drift: mixing old and new model embeddings in one index produces corrupted retrieval (failure_modes/embedding_drift.yaml)

Evidence grounding

Grounded, 2 supporting items

Updating the embedding model without full re-indexing mixes incompatible vector spaces.
