为什么选择GaussDB向量数据库

华为向量检索性能第一

高性能：ann-benchmarks打榜第一。
云原生：云上深耕超3年
高精度：自研向量引擎、支持Flat、PQ、IVF-PQ、Graph、IVF-Graph等索引类型，并采用创新的裁边、联边构图方式；支持文本向量混合索引查询。
高性价比：支持存算分离，冷数据存储成本下降80% ; 基于PQ量化算法，内存相比ES算法降低70%。

语义检索效果领先

大规模相关性数据构建：高质量相关性标注数据，包含正负例假正例去除，去除相关性不是特别高的数据难负例构建，和query相关，但不是正确答案假负例去除，未在数据集中被标注的，但是与query相关的文档。
引入动态难负例训练：采用动态难负样本优化召回模型，进一步推升模型效果。

应用场景

向量检索

向量检索的应用场景非常广泛，典型如：语义搜索、图像搜索、商品推荐、智能客服、企业知识库搜索等等。

优势

大模型的“黄金搭档”

为盘古大模型提供缓存能力，同时提供开箱即用的多模态Embedding能力。

高效可靠

华为自研向量检索引擎，提供极致的搜索性能以及分布式容灾能力。

索引丰富

支持多种索引算法及相似度度量方式，满足各类应用场景及需求。

0学习成本

完全兼容开源ES语法与生态。
