pgvector HNSW索引在并发写入和向量归一化方面存在问题

作者 PulseAugur 编辑部 · [3 个来源] ·

一位开发人员在集成AI求职管道时，遇到了pgvector的Hierarchical Navigable Small World (HNSW)索引在处理并发写入时出现的严重性能问题。问题并非源于查询延迟，而是索引维护过程，其中并发插入导致锁等待，从而饿死了其他作业。第二个问题被确定为不同嵌入客户端之间向量归一化不一致，导致排名不正确。修复方法包括在写入边界强制执行归一化，并优化摄取操作的事务大小。 AI

影响 凸显了依赖向量数据库进行实时数据摄取和检索的AI应用程序可能面临的扩展性挑战。
