Console

Console 数据接收器

支持连接器版本

• 所有版本

支持的引擎

Spark
Flink
SeaTunnel Zeta

描述

接收Source端传入的数据并打印到控制台。支持批同步和流同步两种模式。

例如，来自上游的数据为 [age: 12, name: jared] ，则发送到控制台的内容为: {"name":"jared"，"age":17}

主要特性

• 精确一次

接收器选项

名称	类型	是否必须	默认值	描述
common-options		否	-	Sink插件常用参数，请参考 Sink常用选项 了解详情
log.print.data	boolean	否	-	确定是否应在日志中打印数据的标志。默认值为true
log.print.delay.ms	int	否	-	将每个数据项打印到日志之间的延迟(以毫秒为单位)。默认值为0

任务示例

简单示例:

随机生成的数据,包含两个字段，即 name（字符串类型）和 age（整型），写入控制台，并行度为 1

env {
  parallelism = 1
  job.mode = "STREAMING"
}

source {
  FakeSource {
    result_table_name = "fake"
    schema = {
      fields {
        name = "string"
        age = "int"
      }
    }
  }
}

sink {
  Console {
    source_table_name = "fake"
  }
}

多数据源示例：

多数据源示例，通过配置可以指定数据源写入指定接收器

env {
  parallelism = 1
  job.mode = "STREAMING"
}

source {
  FakeSource {
    result_table_name = "fake1"
    schema = {
      fields {
        id = "int"
        name = "string"
        age = "int"
        sex = "string"
      }
    }
  }
   FakeSource {
    result_table_name = "fake2"
    schema = {
      fields {
        name = "string"
        age = "int"
      }
    }
  }
}

sink {
  Console {
    source_table_name = "fake1"
  }
  Console {
    source_table_name = "fake2"
  }
}
