flume custom Interceptor

Implement an interface

接口：org.apache.flume.interceptor.Interceptor

方法1：Event intercept(Event var1);

Event processing is a data structure flume data message byte to the presence of body Event

The method enables the processing logic for each message, to be achieved.

 

方法2：List<Event> intercept(List<Event> var1);

The method enables the processing of a batch message, when the batch is Flume pull message will be processed by this method must be implemented

 

Interceptor provide examples of access

   public static class Builder implements Interceptor.Builder {

        public Interceptor build() {
            return new SimpleDataTransformInterceptor();
        }

        public void configure(Context context) {
        }

    }

　　

Builder must be achieved in our internal Interceptor class as an inner class

 

Configuration takes effect

a${agent_name}.sources.${source_name}.interceptors = ${interceptor_name}

${agent_name}.interceptors.${interceptor_name}.type=com.test.interceptor.MyInterceptor$Builder
