Main memory database systems (or in memory database system, IMDS) are the vanguards to leverage the big memory for higher data processing performance (Li & Patel, 2013; Balkesen, Teubner, Alonso, & 脰zsu, 2013).
硬件架构不能指望计算量一大，就扩展CPU，存储量一大，就用内存堆砌的方式；这是一种对过去架构的严重依...
减少存储器乃至IO的延迟，提高带宽。这是所有存储器商场、IO设备厂商一直在做的事情。现在的计算讲的最...

By using in-memory technologies, you can achieve performance improvements with various workloads:Transactional (online transactional processing (OLTP)) where most of the requests read or update smaller set of data, for example, create/read/update/delete (CRUD) operations. Analytic (online analytical ...
What is an in-memory database? IMDBs are high-speed data storage systems with all data in the computer’s main memory for fast data retrieval and processing.
Oracle Database In-Memory(In-Memory数据库)最先是在Oracle Database 12c第1版(12.1.0.2)中引入的功能,可大大提高实时分析和混合工作负载的性能。 In-Memory列存储(IM列存储)是Database In-Memory的关键功能。 分析应用程序的挑战 传统方面,为分析查询获得良好的性能意味着能够满足许多要求。
Oracle Database In-Memory implements state-of-the-art algorithms for in-memory scans, joins, and aggregation. These optimizations, along with SIMD vector processing, enable Oracle Database In-Memory to run queries at billions of rows per second for each CPU core. Analytics that previously took ...
韩国的Sung-Joon Jang 团队在《HAIL-DIMM: Host Access Interleaved with Near-Data Processing on DIMM-based Memory System》中介绍了HAIL-DIMM,一种基于LRDIMM的NDP(Near-Data Processing, 近数据处理)架构,旨在减少主机与存储之间的数据移动开销,同时确保系统公平性。HAIL-DIMM通过使用现有内存控制器的BANK 交叉存取...
随着Oracle 12c推出了in memory组件,使得Oracle数据库具有了双模式数据存放方式,从而能够实现对混合类型应用的支持:传统的以行形式保存的数据满足OLTP应用;列形式保存的数据满足以查询为主的OLAP应用。in memory组件可以和其他数据库组件功能使用,并不需要用户单独开发或者修改应用程序,就可以非常方便的实现基于实时数据库分...
