Nova: A Multi-Purpose Vector Engine for Low-Latency, Multi-Tenant, and Cross-Table Hybrid Retrieval

Summary: Nova’s dual-layer delta–base architecture decouples ingestion and indexing, providing immediate visibility and lock-free, low-latency queries under bursty, multi-tenant workloads. As a relational optimizer citizen, it supports cross-table hybrid retrieval via adaptive joins and tiered memory/disk storage. (summarized by gpt-5.6-luna on Aug 28 2026)
