How to Keep RAG Search Fresh When Data Drifts
A developer outlines four strategies to maintain RAG pipeline accuracy as data evolves: scheduled full rebuilds, incremental upserts, embedding version registry, and approximate staleness detection. The corpus of 50M chunks costs $800 and 4 hours for a full rebuild. The post highlights the trade-off between freshness and cost in production AI systems.

The post frames a common production headache—stale embeddings—but the real challenge is that none of the proposed solutions address the underlying cost of frequent rebuilds at scale.
