Description

Used to send data to Console. Both support streaming and batch mode.

For example, if the data from upstream is [age: 12, name: jared], the content send to console is the following: {"name":"jared","age":17}

Key Features

Options

Name Type Required Default Description
common-options No - Sink plugin common parameters, please refer to Sink Common Options for details
log.print.data boolean No - Flag to determine whether data should be printed in the logs. The default value is true
log.print.delay.ms int No - Delay in milliseconds between printing each data item to the logs. The default value is 0.

Task Example

Simple:

This is a randomly generated data, written to the console, with a degree of parallelism of 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"
  }
}

Multiple Sources Simple:

This is a multiple source and you can specify a data source to write to the specified end

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"
  }
}
