Description
OneSparse is a unified system developed for efficient multi-index vector search, directly addressing performance and scalability challenges in large-scale vector databases. It is particularly relevant for applications such as recommendation systems and search engines that require efficient retrieval from hybrid data sets containing both sparse and dense vectors.
Features
- Unified Multi-Vector Index Query System: Integrates multiple posting-based vector indices to enable efficient retrieval from multi-modal datasets.
- Novel Query Engine Design: Introduces inter-index intersection push-down, a technique that allows for more efficient joint searches across multiple indices.
- Optimized Vector Posting Format: Enhances the performance of multi-index queries by optimizing how vectors are stored and accessed.
- Performance Improvement: Achieves over 6× search performance improvement compared to traditional approaches, while maintaining comparable accuracy.
- Real-world Deployment: Integrated into Microsoft online web search and advertising systems, resulting in significant latency reduction (5×+ for Bing web search) and increased revenue metrics (2.0% RPM gain for Bing sponsored search).
- Supports Hybrid Queries: Designed for multi-modal queries and multi-model ensemble queries, allowing joint search on multiple vector indices (e.g., sparse and dense vectors).
- Addresses Limitations of Existing Methods: Overcomes inefficiencies and algorithmic limitations of isolated search and vector fusion approaches.
- Efficient Approximate Nearest Neighbor (ANN) Search: Supports fast and accurate approximate Top-K queries across multiple indices.
- Minimizes Redundant Computation: Reduces unnecessary disk I/O and score computation by optimizing intersection and ranking processes.
