介绍

• 是一种向量数据库

• Milvus是在2019年创建的，其唯一目标是存储、索引和管理由深度神经网络和其他机器学习（ML）模型生成的大规模嵌入向量。

• 作为一个专门设计用于处理输入向量查询的数据库，它能够处理万亿级别的向量索引。

docker 安装 Milvus 并使用 Attu 可视化工具

• 使用docker-compose安装

  • docker-compose -f milvus-standalone-docker-compose.yml up -d

• 本地浏览器启动 http://localhost:8000/

  • Milvus的host是默认的， 用的是docker container name [所有的容器都在一个网络下，所以可以这样访问]
