Netflix’s decision to decouple raw video ingestion from multimodal AI data fusion serves as a masterclass in pipeline architecture. By persisting raw model outputs into Cassandra first and relying on asynchronous “temporal bucketing” to align intersecting predictions offline, they prevent complex intersections from bottlenecking their real-time 216-million-frame ingest layer.

PAR Technology demonstrated a masterclass in LLM multi-tenant security by introducing a “Split-Plane SQL” architecture. Instead of trusting a non-deterministic LLM to apply tenant filters, they programmatically generate row-level security CTEs before the model is invoked, giving the LLM zero visibility into cross-tenant data and completely neutralizing prompt-injection data leaks.
