Bridging the Gap: Enabling Natural Language Queries for NoSQL Databases through Text-to-NoSQL Translation
Researchers have introduced TEND, the first execution-verified benchmark for Text-to-NoSQL translation, comprising 1,210 MongoDB-native tasks. They also propose SAG, a Schema-as-Data Grounding solver, to improve query generation for schema-less document stores. Experiments show that LLMs strong at NL2SQL struggle on TEND, validating Text-to-NoSQL as a distinct problem.
Semantic Pyramid Indexing: Adaptive Query Depth for Streaming RAG in Vector Databases
Researchers propose Semantic Pyramid Indexing (SPI), a vector database indexing framework that adapts retrieval depth per query in streaming RAG pipelines. SPI organizes embeddings into semantic resolution levels, reducing average latency by 1.4–2.3× at fixed Recall@10 on standard benchmarks, and demonstrates 6.2× throughput scaling on 8 nodes. The framework supports incremental updates and is compatible with FAISS and Qdrant backends.
Technology Supabase Raises $500M at $10B Valuation, Doubling in 8 Months on Vibe-Coding Boom
Supabase, the open-source Postgres database platform, raised $500 million at a $10 billion pre-money valuation, doubling its valuation in eight months. The company attributes its growth to the rise of vibe-coding tools like Claude Code and Codex, which have driven database launches up 600% year-over-year, with over 60% launched by AI tools. Supabase also launched Multigres, an operating system for Postgres, to ease scaling complexity.
