The key trade-off in the storage layer design of vector databases lies in the division of labor between memory and disk: an all-in-memory approach has the lowest latency but high cost, a disk-based approach relies on mmap and prefetching strategies, and a hybrid approach balances the two through tiered caching.

UnverifiedThe storage layer of a vector database must simultaneously carry raw vectors, metadata, and index structures, and raw vectors are usually stored contiguously as fixed-length arrays to support SIMD instruction acceleration of distance computation.79% similarUnverifiedDisk index size refers to the space the index files occupy on persistent storage, which determines deployment cost, backup and migration burden, and cold-start loading time; in-memory residency refers to the size of the data structures that must be loaded into RAM during queries, which directly affects the number of concurrent queries a single machine can handle and hardware selection.79% similarUnverifiedDedicating the vector store to semantic recall while maintaining a separate relational table for success rate statistics linked via work order ID offers clear separation of responsibilities and more efficient aggregation queries, at the cost of needing to keep writes to both stores synchronized when work orders are archived76% similarUnverifiedDecoupling storage from compute allows teams to independently select a cheaper storage tier for cold data without being forced to upgrade expensive compute instances when expanding storage.75% similar
