Overview ¶
Package pinecone 提供 Pinecone 向量数据库集成
Pinecone 是一个托管的向量数据库服务，专为生产级向量搜索而设计。
特性：
- 完全托管，无需运维
- 亚毫秒级查询延迟
- 自动扩缩容
- 支持元数据过滤
- 支持命名空间隔离
使用示例:
store, err := pinecone.NewStore(ctx,
pinecone.WithAPIKey("your-api-key"),
pinecone.WithEnvironment("us-west1-gcp"),
pinecone.WithIndex("my-index"),
)
defer store.Close()
