Druid是一个快速的列式分布式的支持实时分析的数据存储系统，在处理PB级别数据、毫秒级查询、数据实时处理方面，比传统的OLAP系统有了显著的性能改进。
与Druid架构相辅相成的是其基于DataSource与Segment的数据结构，它们共同成就了Druid的高性能优势。

安装部署
imply集成了Druid，提供了Druid从部署到配置到各种可视化工具的完整的解决方案，imply有点类似于我们之前学过的Cloudera Manager
启动zookeeper
启动imply：
[kris@hadoop101 imply-2.7.10]$ bin/supervise -c conf/supervise/quickstart.conf [Fri Jan 3 13:37:51 2020] Running command[coordinator], logging to[/opt/module/imply-2.7.10/var/sv/coordinator.log]: bin/run-druid coordinator conf-quickstart [Fri Jan 3 13:37:51 2020] Running command[broker], logging to[/opt/module/imply-2.7.10/var/sv/broker.log]: bin/run-druid broker conf-quickstart [Fri Jan 3 13:37:51 2020] Running command[historical], logging to[/opt/module/imply-2.7.10/var/sv/historical.log]: bin/run-druid historical conf-quickstart [Fri Jan 3 13:37:51 2020] Running command[overlord], logging to[/opt/module/imply-2.7.10/var/sv/overlord.log]: bin/run-druid overlord conf-quickstart [Fri Jan 3 13:37:51 2020] Running command[middleManager], logging to[/opt/module/imply-2.7.10/var/sv/middleManager.log]: bin/run-druid middleManager conf-quickstart [Fri Jan 3 13:37:51 2020] Running command[imply-ui], logging to[/opt/module/imply-2.7.10/var/sv/imply-ui.log]: bin/run-imply-ui-quickstart conf-quickstart
说明：每启动一个服务均会打印出一条日志。可以通过/opt/module/imply-2.7.10/var/sv/查看服务启动时的日志信息

查看端口号9095的启动情况：
[kris@hadoop101 sv]$ netstat -anp | grep 9095 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 :::9095 :::* LISTEN 6118/imply-ui-linux tcp 0 0 ::ffff:192.168.1.101:9095 ::ffff:192.168.1.1:54884 TIME_WAIT - tcp 0 0 ::ffff:192.168.1.101:9095 ::ffff:192.168.1.1:54883 TIME_WAIT -
登录hadoop101:9095查看
停止服务
按Ctrl + c中断监督进程，如果想中断服务后进行干净的启动，请删除/opt/module/imply-2.7.10/var/目录。
