Vector Cache
A performance layer that temporarily stores frequently requested embeddings or retrieval results for faster access.
A vector cache is used to reduce latency in high-traffic semantic search and RAG systems. Instead of recomputing the same queries or embedding transformations repeatedly, results can be stored temporarily. This improves user experience while also potentially lowering infrastructure cost. However, cache validity and data freshness must be managed carefully.
