#VectorStore
We let each Layer Index choose its upstream VectorStore with `spec.backend.storeRef`. Namespaces without that reference use the default store. The gateway routes the request; the caller keeps one endpoint. https://hevlayer.com/docs/kubernetes/vectorstore-crd
October 26, 2026 at 10:22 PM
Layer's Pipeline CRD lets extract/chunk and embed workers share one gateway queue through pipelineId. CPU extraction stages chunks; GPU embedding claims pending documents and writes vectors to the target VectorStore. https://hevlayer.com/docs/kubernetes/pipeline-crd
September 28, 2026 at 11:44 AM
Layer's query API takes nearest_to_id instead of a raw vector: pass stored document ids and rank by their own vectors. The gateway resolves each id from the document cache first, falling back to the namespace's VectorStore on a miss. https://hevlayer.com/docs/api/query

100 Spring AI Project Ideas You Can Build Without Touching Python
Most Java developers think building AI features means learning Python first. It doesn't. **Spring AI** gives you `ChatClient`, `VectorStore`, function calling, and structured output — inside the same Spring Boot app you already know how to build, test, and deploy. You don't need to bolt on a separate Python service just to add a chatbot, a RAG pipeline, or an agent to your product. To make that concrete, I put together **100 project ideas** you can build with Spring Boot and Spring AI. Not vague titles — each one comes with the actual stack you'd reach for. Here are five, to give you a feel for the format: Project | Stack ---|--- Support Bot with RAG | Spring AI + pgvector + `QuestionAnswerAdvisor` Meeting Notes Summarizer | `BeanOutputConverter` → `ActionItem` records Natural Language to SQL | JDBC `DatabaseMetaData` for schema context Repo-Aware Coding Agent | Tree-sitter + `VectorStore` + function calling Voice Support Agent | WebSocket audio + RAG + function calling ## The three tiers The full list is organized by difficulty, so you can pick something that matches where you are right now instead of jumping straight into agent orchestration: * **1–40 · Beginner** — Spring Boot + Spring AI fundamentals: your first `ChatClient` calls, prompt templates, basic conversational endpoints. * **41–80 · Intermediate** — RAG pipelines and integrations: vector stores, document ingestion, structured output, calling external APIs from a model. * **81–100 · Advanced** — Agents and orchestration: multi-step reasoning, tool-calling agents, and systems that coordinate several models or services. ## Why I'm doing this project by project I'm building these one at a time — real code, real architecture decisions, and the parts that break along the way (because something always does). Each finished project gets a full write-up: what I built, the tradeoffs I hit, and the code itself. **Want the full list of all 100 projects (with stacks) as a PDF?** Download it here — save it for later. If you want to follow along as the series grows, I'm publishing every project on my Substack the day it's done — subscribe here to get each one as it lands. I also run a small community for Java developers building with Spring Boot and Spring AI, if you want to talk through ideas or share what you're building: Global Java Developers Community. ## **Which one should I build first?** Drop a number (or a project idea of your own) in the comments — I'm picking the next build from replies.

施主,我懂 document versioning 是啥,但這個 document,跟 LangChain 的 Document,跟 ChromaDB 的 Document,甚至候選的某某 SQL 的 Document,好像不是同一個概念?一邊搞 LangChain 一邊拿那個 VectorStore 做 CRUD 是不是... 有點跳脫?
(尤其是 LangChain 的文檔跟 LLM 一樣,存在大量幻覺)

i just purged a ton of jank bridgy fed standard.site documents from the vectorstore for pub-search.waow.tech so now the semantic search results are a lot better, which, notably will improve results for anyone using the pub-search MCP -> protopack

however, back in the day we had vectorstore support in marvin and though we later slimmed it down to just structured outputs, i've been maintaining / using the vectorstore / document ingestion utils here for a while now

oh ok i think i interpreted the question more broadly (using LLMs in general) but as far as controlflow I think the only vectorstore support is an implementation detail of memory so I suspect that section might be old / LLM hallucinated 🙂

but @jlowin.dev might correct me

Moving my small demo app to Spring AI 1.0.0 M5 was smooth.
Only had to change the call to VectorStore.

Next step is to try out the new audio support.
