REL_FAILURE:这是对处理器定义的“失败”关系的引用。和REL_SUCCESS一样,它也可以通过引用父类(ExecuteScript)的静态成员来继承,但是一些引擎(如Lua)不允许引用静态成员,所以这是一个方便的变量。这也节省了必须使用关系的完全合格的名称。 Dynamic Properties : 在ExecuteScript中定义的任何动态属性都将作为设置为与...

分析： 1，变量控制 这个很简单，在线程执行进入的时候，写控制变量running = true。线程将要退出的时候...
2) If you want to build a single statement with possibly multiple parameters, you could use ExecuteScript (if you are comfortable writing code in Groovy, Jython, JRuby, JavaScript, or Lua) to read in the configuration file, split the lines to build a map of parameter names to values, the...
Run a full NiFi build (see above for instructions). Then from the minifi/ subdirectory, executemvn -P docker clean install. This will run the full build, create a docker image based on it, and run docker-compose integration tests. After it completes successfully, you should have an apache...
2.3.3 数据接入类处理器单元 ConvertJSONToSQL ConvertJSONToSQL处理器单元可以将结构化的Json转换成INSERT或者UPDATE这样命令的SQL,配合PutSQL处理器单元可以直接根据这鞋命令将数据插入数据库中。 上面的图中表示Processor根据输入的FlowFile的JSON内容,将JSON转化成Update的SQL语句。 ExecuteSQL Exec... ...
