Qdrant是一家开源向量数据库初创公司，拥有超过1000万次安装量。我们与创始人兼CEO Andre Zayarni 进行了对话，深入了解Qdrant与通用数据库的差异化优势。 AI管道需要处理结构化、文件和对象数据。Zayarni指出，AI管道越来越关注非结构化数据——文件、 文档、图像和代码，这些构成了模型训练和实时推理任务的骨干。结构化数据（如元数据）通常用于标 记、过滤或组织内容，以实现更好的检索和控制。 向量化与存储策略 关于数据向量化，Zayarni建议使用与任务和领域相匹配的嵌入模型。一旦转换为向量，这些数据变得 庞大、固定大小且在计算上密集。"通用数据库从根本上不适合高维相似性搜索，它们缺乏实时大规模 检索所需的索引结构、过滤精度和低延迟执行路径。" 相比之下，专用向量数据库专为此挑战而构建，提供一阶段过滤、混合搜索、量化和智能查询规划等功 能。 部署环境选择 AI数据管道的核心阶段 在谈到AI训练和推理数据管道时，Zayarni强调区分训练和推理的重要性。"训练管道负责准备原始数据 以微调或预训练基础模型，而推理管道专注于将这些模型应用到实际任务中。"向量搜索是推理阶段的 核心：从相关数据 ...

Let's talk a little bit about today. Lakebase was sort of I thought it was really interesting that makes data more useful for the AI era, but it also brings you onto the home turf of really big tech companies like Oracle and Microsoft and Amazon. What gives you the confidence that you can compete with these guys in their own backyard.Yeah, I mean so basically this technology hasn't changed for 40 years. It's been basically the same and you know it's so locked in. Once you have your data there, you can't mov ...

OceanBase积极拥抱MCP协议，其推出的OceanBaseMCPServer已集成至阿里云魔搭、anserPACK等官方 平台，能与各类MCP客户端共同使用。开发者通过自然语言对话可直接与数据库交互。 OceanBaseCTO杨传辉表示，OceanBase正以"DataxAI"战略为支点，构建一体化数据底座。一方面通过 AI技术提升数据库自身的智能化水平（如智能使用、智能运维、智能开发等），让数据库更"聪明"；另 一方面通过技术适配与功能创新，与AI生态深度耦合，让数据库更"强大"，降低AI落地门槛。2025年4 月，OceanBase宣布公司全面进入AI时代，并正式启动"DataxAI"战略。 （文章来源：证券日报） 本报讯 （记者李冰）日前，OceanBase公布在AI生态领域取得阶段性进展，该公司目前已与 LlamaIndex、LangChain、Dify等全球60余家AI生态伙伴深度集成，并支持大模型生态协议MCP，逐步 构建起从模型到应用覆盖数据全生命周期的智能能力。这是OceanBase在公布DataxAI战略后，首次对外 透露战略落地进展。 "OceanBase走过15年自研道路，这个过程 ...

最近，我发现身边很多DBA朋友"消失"了——有的转行做了架构师，有的跳槽去了业务部门，还有人干 脆离开了IT行业。他们的离开让我不禁思考：为什么曾经在数据库领域深耕的"技术宅"们，如今却纷 纷"弃库而去"？ 是技术迭代太快，还是我们走错了方向？ 1.国内DBA的困境 一位老DBA曾自嘲："我们就像数据库的'保姆'，从装系统、调参数、写SQL到扛故障，样样都得会， 但样样都不精。"这句话道出了国内DBA的普遍现状——技术广度远超深度。 职责泛化：国内企业往往要求DBA"全能"。从安装配置、备份容灾到性能优化，甚至业务需求分析， DBA被赋予了太多角色。而国外DBA则更注重细分领域，比如Oracle调优专家、MySQL集群架构师 等。 技术浮躁：面对云原生、分布式数据库的浪潮，许多DBA疲于学习新工具，却忽视了底层原理的钻 研。一位资深DBA坦言："会用工具不等于懂技术，就像会开车的司机未必懂发动机原理。" 价值倒挂：国内许多DBA仍被视为"救火队员"，薪资与复杂度不匹配，而国外专精型DBA因解决核心 问题（如优化一条SQL节省数百万硬件成本）被视为"技术资产"。 2.技术深耕 广度是生存的基础，深度才是突破的天 ...
