Previous works do not relate to function pointers, but reading some documents reading and learning STL functions lets me know the pointer of functions is broadly used in functions such as XXX_if(). I don't think it's really that difficult, but it rea…
1.简介 Phoenix是一个HBase框架,可以通过SQL的方式来操作HBase. Phoenix是构建在HBase上的一个SQL层,是内嵌在HBase中的JDBC驱动,能够让用户使用标准的JDBC来操作HBase. Phoenix使用JAVA语言进行编写,其查询引擎会将SQL查询语句转换成一个或多个HBase Scanner,且并行执行生成标准的JDBC结果集. *如果需要对HBase进行复杂的操作,那么应该使用Phoenix,其会将SQL语句转换成HBase相应的API. *Phoenix…
本文将解析<完美图解物联网Iot实操 ESP8266>中 第五章 P177页 动手做的代码2(使用SPIFFS文件系统的代码) 首先我们先动手使用Arduino IDE编译并且上传代码,上传后记得使用工具中ESP8266 SPIFFS上传工具上传SPIFFS文件夹的内容,否则应用将无法使用.你很有可能看到下面这样的画面. FileNotFind 默认的404页面 至于为什么后面会详细说明,如果上传SPIFFS文件夹上传成功,访问你的ESP8266的IP看到的应该是这样的画面. 正常页面 下面我…

hbase 提供很方便的shell脚本,可以对数据表进行 CURD 操作,但是毕竟是有一定的学习成本的,基本上对于开发来讲,sql 语句都是看家本领,那么,有没有一种方法可以把 sql 语句转换成 hbase的原生API呢? 这样就可以通过普通平常的 sql 来对hbase 进行数据的管理,使用成本大大降低.Apache Phoenix 组件就完成了这种需求,官方注解为 “Phoenix - we put the SQL back in NoSql”,通过官方说明,Phoenix 的性能很高,相…
Hadoop生态圈-phoenix完全分布式部署 作者:尹正杰 版权声明:原创作品,谢绝转载!否则将追究法律责任. phoenix只是一个插件,我们可以用hive给hbase套上一个JDBC壳,但是你有没有体会到Hive执行SQL语句是很慢的,因此我们采用phoenix插件的方式给hbase套上JDBC的壳. 一.Phoenix简介 1>.其实Phoenix可以看成是在hbase的hive,它是使用SQL方式访问HBase数据: 2>.内置多种协处理器实现,轻松实现二级索引和聚合查询: 二.部…

一.Phoenix简介 Phoenix是HBase的开源SQL中间层,它允许你使用标准JDBC的方式来操作HBase上的数据.在Phoenix之前,如果你要访问HBase,只能调用它的Java API,但相比于使用一行SQL就能实现数据查询,HBase的API还是过于复杂.Phoenix的理念是we put sql SQL back in NOSQL,即你可以使用标准的SQL就能完成对HBase上数据的操作.同时这也意味着你可以通过集成Spring Data JPA或Mybatis等常用的持久层…
