Sink Common Options

Common parameters of sink connectors

name	type	required	default value
source_table_name	string	no	-
parallelism	int	no	-

source_table_name [string]

When source_table_name is not specified, the current plug-in processes the data set dataset output by the previous plugin in the configuration file;

When source_table_name is specified, the current plug-in is processing the data set corresponding to this parameter.

parallelism [int]

When parallelism is not specified, the parallelism in env is used by default.

When parallelism is specified, it will override the parallelism in env.

Examples

source {
    FakeSourceStream {
      parallelism = 2
      result_table_name = "fake"
      field_name = "name,age"
    }
}

transform {
    Filter {
      source_table_name = "fake"
      fields = [name]
      result_table_name = "fake_name"
    }
    Filter {
      source_table_name = "fake"
      fields = [age]
      result_table_name = "fake_age"
    }
}

sink {
    Console {
      source_table_name = "fake_name"
    }
    Console {
      source_table_name = "fake_age"
    }
}

If the job only have one source and one(or zero) transform and one sink, You do not need to specify source_table_name and result_table_name for connector. If the number of any operator in source, transform and sink is greater than 1, you must specify the source_table_name and result_table_name for each connector in the job.
