Streamer

The

Streamer

component splits text input into segments. It passes each type of segment to a predefined transformation such as a Parser, mapper, or serializer.

The

Streamer

must be defined at the global level of the Script and it must be the startup component of the transformation.

Under a

Streamer

, you must nest a

ComplexSegment

. The

ComplexSegment

can contain nested

SimpleSegment

ComplexSegment

components.

The following table describes the properties of the

Streamer

component:

Property	Description
contains	Defines the overall structure of the source. Default is ComplexSegment.
disabled	Determines whether the Script ignores the component and all of the child components. Use this property to test, debug, and modify a Script. You can choose one of the following options: Selected. The Script ignores the component. Cleared. The Script applies the component. The default is cleared.
max_lookup_size	Defines the maximum quantity of new data, in kilobytes, that the Streamer searches for each new segment. For optimal performance, set this property to twice the maximum possible segment size. When an application activates a deployed Streamer service through an API, it must set the chunk size parameter to a value that is smaller than the max_lookup_size . Default is 10000.
name	A descriptive label for the component. This label appears in the log file and the Events view. Use the name property to identify the component that caused the event.
on_end_of_input	Defines a transformation that runs at the end of the input stream. For example, the transformation can output a summary message. You can choose one of the following options: The name of a Parser, serializer, or mapper that is configured at the global level of the Script. A Mapper or Serializer component. Configure the mapper or serializer within the Streamer.
remark	A user-defined comment that describes the purpose or action of the component.
root_tag	Defines an XML tag in which the Streamer wraps the combined output from all the segments. For more information, see Output of a Streamer.
