摘　　要：全超导托卡马克核聚变实验装置(EAST)构造复杂、子系统众多,多源异构的架构下各类数据之间孤立,缺少统一的资源目录,导致用户对数据使用的学习成本极高。该文基于MongoDB创新地反范式化的按炮聚簇设计元数据库,建立了包括实时元数据提取、状态巡检、典型查询封装、日志管理等完整的元数据库服务管理平台。解决了现有装置统一资源目录缺失的问题,实现了对装置各子系统元数据实时更新、管理的功能,降低了用户访问数据的难度,为跨源数据统计和挖掘提供基础架构支持。目前该系统已经在EAST验证并部署应用,并计划应用于下一代中国工程实验堆(CFERT)。EAST has a complex structure and numerous subsystems.Under the multi-source heterogeneous architecture,all kinds of data are isolated,and there is no unified resource catalog.Therefore,users have a high cost of learning data usage.In this paper,based on the innovative anti-formalization of MongoDB to design metadata cluster by shot,the establishment of metadata extraction,database status inspection,typical query encapsulation,log management and a set of metadata service management platform.It solves the problem of missing unified resource catalogue of existing devices,realizes the real-time update and management of metadata of each subsystem of devices,reduces the difficulty of users'access to data,and provides infrastructure support for cross-source data statistics and mining.The system has been validated and deployed in EAST and is planned to be used in the next generation China engineering experimental reactor(CFERT).
