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"
  }
}
