A local index may be prefixed or non-prefixed. A prefixed index is partitioned on the leftmost column(s) in the index. Since a local index, by definition, is partitioned on the same key as the table, a local prefixed index will have the table partition key as its leftmost column. ...
Local non-prefixed indexes will not have the table's partitioning key as their leftmost column. For example: CREATE INDEX deptloc2_idx ON dept(loc) LOCAL; Each partition of a non-prefixed local index will of course potentially contain the full range of possible key values, as shown in th...
2. confirm B area GK prefix, two kind of numbers exist, first is 100 like 100xxx×××; and second is 1000 as prefix, like 1000xxxxx××. Call these two numbers with local number 53xx×××. Number begin with 100 is accessible, but number begin with 1000 prompt that the number ...

用过Impala的同学都知道,Impala本身引入了一个catalogd服务,来缓存hms和nn中的一些元数据,例如表的信息、文件信息、block信息等。同时,这份元数据会通过statestored广播到所有的coordinator节点(以下简称c节点),executor节点不需要缓存元数据。这种设计可以极大的提升查询性能,每次SQL解析的时候,不需要再跟hms/nn进行交互...
pathType: Prefix backend: service: name: svc-lb-httpd port: number: 80 4. 在 NSX 应用交付控制器上,可以看到为上述应用创建了 L7 虚拟服务,后端服务器池中 NodeIP:Port 映射方式表明,这采用的是 NodePortLocal 模式。 总结 “ NodePortLocal”( NPL )是 CNI 项目 Antrea 中提出的,可以提高在节点上通过...
--prefix=/usr/local/ssl:这个参数指定了 OpenSSL 的安装目录为/usr/local/ssl。在安装完成后,OpenSSL 可执行文件、库文件和其他相关文件将被放置在该目录下。 --shared:这个参数表示编译共享库(动态链接库)。当使用这个选项时,生成的库文件将以.so(Linux)或.dylib(macOS)的形式存在,而不是静态链接库.a。共享...
Local-Pref(本地优先属性)路由本地优先术: ①:抓取感兴趣流量——前缀与访问——prefix and access ②:创建路由地图——router-map ③:第一法则——permit 10 ④:第一法则中,匹配(感兴趣)流量。——match ⑤:第一法则中,设置本地优先术——local

软件不一样，默认是不一样的 ./configure --help 可以查看./configure 的默认参数,可以看到prefix的默认值 ./configure --prefix=DIR 可以设置安装目录为DIR,例如./configure --prefix=/usr/local
