DataWorks中Elasticsearch Reader基本配置是什么？

注意 实际运行时，请删除下述代码中的注释。{"order":{"hops":[{"from":"Reader","to":"Writer"}]},"setting":{"errorLimit":{"record":"0" //错误记录数。},"jvmOption":"","speed":{"concurrent":3,//并发数"throttle":true,//"mbps":"12",//限流}},"steps":[{"category":"reader","name":"Reader","parameter":{"column":[ //读取列。"id","name"],"endpoint":"", //服务地址。"index":"", //索引。"password":"", //密码。"scroll":"", //scroll标志。"search":"", //查询query参数，与Elasticsearch的query内容相同，使用_search api，重命名为search。"type":"default","username":"" //用户名。},"stepType":"elasticsearch"},{"category":"writer","name":"Writer","parameter":{ },"stepType":"stream"}],"type":"job","version":"2.0" //版本号。}
