Milvus【部署 01】向量数据库Milvus在Linux环境下的在线+离线安装

1.千问简介

Milvus 是一款专为处理高维向量数据设计的开源云原生数据库，旨在满足海量向量数据的实时召回需求。它由 Zilliz 公司开发并维护，基于Apache许可证2.0版本发布。Milvus的核心能力在于其高可用性、高性能及易拓展性，特别优化了对由深度神经网络和其他机器学习模型生成的嵌入（embedding）向量的管理、搜索和操作。

该数据库底层集成了诸如 FAISS、Annoy、HNSW 等高效的向量搜索库，用以解决稠密向量的相似度检索问题。通过支持数据分片、数据持久化、增量数据摄取、标量与向量混合查询以及时间旅行查询（time travel）等功能，Milvus能够应对复杂多变的向量检索场景，并且显著提升向量检索性能。

Milvus广泛应用于需要高效处理非结构化数据检索的领域，如推荐系统、图像检索、语音识别、自然语言处理、语义搜索等人工智能应用场景。为了实现最佳的可用性和弹性，通常建议通过Kubernetes来部署Milvus。其采用的共享存储架构将存储与计算分离，进一步增强了系统的灵活性和扩展性。
