向量存储(VectorStore)是一种用于存储和检索高维向量数据的数据库或存储解决方案,它特别适用于处理那些经过嵌入模型转化后的数据。在 VectorStore 中,查询与传统关系数据库不同。它们执行相似性搜索,而不是精确匹配。当给定一个向量作为查询时,VectorStore 返回与查询向量“相似”的向量。 VectorStore 用于将您的数据与
How does a vector store work? In a vector store, vector search algorithms are used to index and query embeddings. Some well-known vector search algorithms include Hierarchical Navigable Small World (HNSW), Inverted File (IVF), DiskANN, etc. Vector search is a method that helps you find simil...
Microsoft.Extensions.VectorData.VectorStoreCollection<TKey, TRecord> Microsoft.Extensions.VectorData.IVectorSearchable<TRecord> 请注意,VectorStoreCollection<TKey, TRecord>实现了IVectorSearchable<TRecord>,所以只需要两个继承类。 应使用以下命名约定: {数据库类型}VectorSto...
ChromaVectorStoreProperties提供了spring.ai.vectorstore.chroma,它从CommonVectorStoreProperties继承了initializeSchema属性,自己提供了collectionName属性 小结 Spring AI提供了spring-ai-starter-vector-store-chroma用于自动装配ChromaVectorStore。要注意的是embeddingDimension默认是1536,如果出现cannot unpack non-iterable corou...
