   R Radar is an electronic device that detects planes, ships, coastlines, landmarks, and even storm clouds. The name radar comes from the first letters of the words radio direction and ranging. As the human eye uses light waves to see, radar "sees" with radio waves. Without radar, planes could not land safely in bad weather and ships could not move safely in thick fog.    R

创建增量Cube的过程和创建普通Cube的过程基本类似，只是增量Cube会有一些额外的配置要求

Kylin 可以在 Hadoop 集群的任意节点上启动。方便起见，您可以在 master 节点上运行 Kylin。但为了更好的稳定性，我们建议您将 Kylin 部署在一个干净的 Hadoop client 节点上，该节点上 Hive，HBase，HDFS 等命令行已安装好且 client 配置（如 core-site.xml，hive-site.xml，hbase-site.xml及其他）也已经合理的配置且其可以自动和其它节点同步。   E   N

Apache Kylin目前提供的Cube构建引擎有两种：MapReduce和Spark(如图2-20所示)。如果你的 Cube只有简单度量（如SUM、 MIN、MAX)，建议使用Spark。如果Cube中有复杂类型度量（如COUNT DISTINCT、 TOP_N），建议使用MapReduce。   S

OLAP（Online Analytical Process），即联机分析处理，它可以以多维度的方式分析数据，并且能弹性地提供上卷（Roll-up）、下钻（Drill-down）和透视分析（Pivot）等操作，是呈现集成性决策信息的方法，其主要功能在于方便大规模数据分析及统计计算，多用于决策支持系统、商务智能或数据仓库。与之相区别的是联机交易处理（OLTP），联机交易处理侧重于基本的、日常的事务处理，包括数据的增、删、改、查。
