实时处理(Real-time processing):实时处理指的是在数据生成或收到后立即进行处理的过程。在这种处理方式中,数据处理的延迟非常低,以便及时作出响应。实时处理通常用于对数据实时监控、控制系统和实时决策等场景。 流数据处理(Streaming data processing):流数据处理是一种处理大量连续输入数据的技术,这些数据通常以数据流...
A real-time database provides the predictable, high speed data access required for on-line applications, while providing flexible searching capabilities. The data retrieval routines include the option to read-through-lock to access data in locked data tables, the capability to directly access to ...
The real-time database is a data processing center and also a public data exchange area. The real-time data collected from external devices are sent to the real-time database, and the data of other parts of the system are also from the real-time database.()A.对B.错 相关知识点: 试...
4、实时⼤数据处理real-time big data processing (RTDP)框架 本⽂根据实时⼤数据处理系统对计算能力和时效性的要求,从功能层⾯将RTDP(Real-Time Data Processing)框架划分为Data、 Analytics、Integration和Decision四个层次。 4.1、Data 该层主要负责数据的收集和存储,也包括数据清洗和⼀些简单的数 据分析,...
The invention discloses a real-time data report processing system based on an OPEN3000 system database. An OPEN3000 WEB server is provided with an ORACLE database; an electric energy system server is internally provided with a DB2 (database 2); an input end of a report system server is ...
Local database persistence。例如Samza将状态保存到local database中,并且将变化量写入kafka,再失败后数据从kafka中恢复,因为kafka没有事务特性,所以其只能支持at lease once语义 Remote database persistence。checkpoint和state直接存储在远程的db中例如MillWheel。只要远程db能有事务特性,就能够实现exactly once的语义 ...
