Building Stateless Serverless Vector DBs via Block-based Data Partitioning
Summary: First experimental comparison of data partitioning for stateless FaaS vector DBs, showing clustering-based partitions fail on dynamic/bursty datasets due to complexity and load‑imbalance. Block-based partitioning yields up to 5.8× faster partitioning, ~63% lower costs and Milvus-comparable recall, enabling cost-efficient serverless vector DBs for sparse workloads.
