1.32.Flink其它案例
1.32.1.使用DataGen生成数据
package com.toto.demo.test;

import org.apache.flink.streaming.api.datastream.DataStreamSource;
import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;

import org.apache.flink.streaming.api.functions.source.datagen.DataGeneratorSource;
import org.apache.flink.streaming.api.functions.source.datagen.RandomGenerator;
import org.apache.flink.table.data.RowData;
import org.apache.flink.table.factories.datagen.types.RowDataGenerator;
public class DataGeneratorSourceDemo {
public static void main(String[] args) {
test1();
}
private static void test1() {
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
String[] fieldNames = new String[] { "id", "state", "score" };
DataGenerator<?>[] fieldGenerators = new DataGenerator[] { //
RandomGenerator.intGenerator(0, 100), //
RandomGenerator.booleanGenerator(), //
RandomGenerator.intGenerator(0, 100) //
};
//第一列是DataGenerator对应的数组，第二列字段名称
RowDataGenerator rowDataGenerator = new RowDataGenerator(fieldGenerators, fieldNames);
DataStreamSource<RowData> source =
//DataGeneratorSource中的第一个参数是RowDataGenerator,第二个参数是间隔时间，第三个参数是数据条数
env.addSource(new DataGeneratorSource<>(rowDataGenerator, 10, 20L), TypeInformation.of(RowData.class))
.setParallelism(1);
source.print().setParallelism(2);
try {
env.execute();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
