It lets an application place related data into explicit ring coordinates, then retrieves the bounded nearby working set before vector ranking, filtering, reranking, or LLM context construction. The result is a database designed to reduce the records, bytes, candidate memory, and tokens a request must process. KoutenDB is useful for RAG and AI retrieval, but it is equally suited to tenant-scoped web systems, user detail pages, product data, application state, and any service where related data is known before a read begins. Reduce RAG Search Space, Candidate Memory, and Token Use KoutenDB's core claim is direct: do not rank, transfer, or send unrelated data downstream when the application already knows the relevant locality. A ring is a first-stage retrieval boundary, not merely a collection name or a filter applied after a broad search. Included, reproducible benchmarks show the effect of selecting the correct ring before exact retrieval: Workload Result --- --- 100-ring working-set benchmark scanned records/query 10,000 - 100 (99% reduction) 100-ring memory-pressure benchmark candidate memory/query 93.079 MiB - 0.931 MiB (99% reduction) synthetic RAG benchmark recall 1.000 , scanned/query 8,000 - 1,000 , estimated tokens/query 3,955 - 657 generated AI/RAG JSONL case study recall 1.000 , scanned/query 400 - 40 , estimated tokens/query 615.2 - ","default_branch":null,"files":null,"tree":[],"storefront":"/r/puffball1567","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/puffball1567/koutendb/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
