Document Ingestion Pipeline
The unglamorous half of RAG: parse PDFs and HTML, chunk with overlap, embed, and UPSERT into pgvector. Redis tracks job progress and locks files so two workers never embed the same object. Bad chunks are quarantined instead of silently poisoning retrieval.

Scalability Roadmap
Celery + Redis on one box. pgvector ivfflat.
Parallel parse. GPU optional for OCR. HNSW when vector count grows.
tenant_id on every chunk. Separate queues for large customers.
Files stay in-region. pgvector replica for retrieval. Redis jobs local.
Cost Breakdown
Development Cost
$8,000 – $20,000 (5–10 weeks)
Infrastructure Cost
$180 – $2,000/month (embeddings dominate)
Maintenance Cost
$1,000 – $3,000/month for parsers and re-embed campaigns
