iFVS: Towards Instance-Optimized Filtered Vector Search
Abdullah Al-Mamun, Yeasir Rayhan, Walid G. Aref
Filtered vector search (FVS) is increasingly important in modern AI + DB systems, where vector similarity search is combined with relational predicates. Quantization plays a vital…
Towards a B+-tree with Fluctuation-Free Performance
Lu Xing, Walid G. Aref
Performance predictability is critical for modern DBMSs. Index maintenance can trigger rare but severe I/O spikes. In a B/B+-tree of Height H, due to node split propagation, the co…
Virtual-Memory Assisted Buffer Management In Tiered Memory
Yeasir Rayhan, Walid G. Aref
Tiered memory architectures have gained significant traction in the database community in recent years. In these architectures, the on-chip DRAM of the host processor is typically…
Gen-DBA: Generative Database Agents
Yeasir Rayhan, Walid G. Aref
Leveraging Machine Learning to optimize database systems, referred to as Machine Learning for Databases (ML4DB, for short), dates back to the early 1990s, spanning indexing techniq…
iPDB -- Optimizing Semantic SQL Queries
Udesh Kumarasinghe, Tyler Liu, Ahmed R. Mahmood +2
Structured Query Language (SQL) has remained the standard query language for databases. SQL is highly optimized for processing structured data laid out in relations. Meanwhile, in…
BMTree: Designing, Learning, and Updating Piecewise Space-Filling Curves for Multi-Dimensional Data Indexing
Jiangneng Li, Yuang Liu, Zheng Wang +5
Space-filling curves (SFC, for short) have been widely applied to index multi-dimensional data, which first maps the data to one dimension, and then a one-dimensional indexing meth…
