What is the most effective approach for handling embedding index updates without downtime in vector stores? (Part 2 Focus)

Summary snapshot
Blue-green index deployments, incremental upserts, and vector quantization strategies.
Content snapshot
### Production Strategy - **Incremental Upserts**: Use primary document IDs as vector keys to overwrite existing vectors instantly. - **Blue-Green Reindexing**: When changing embedding models (e.g. text-embedding-ada-002 to text-embedding-3-large), create a parallel vector collection, index offline, and swap alias pointers atomically. *Note: This question represents expanded technical inquiry iteration #2 within the RAG & Vector Databases topic area.* *Note: This question represents expanded technical inquiry iteration #2 within the RAG & Vector Databases topic area.*
