Column Projections Properties

Column Projections Properties

The Developer tool displays the column projection properties in the
Properties
view of the write operation.
To specify column projection properties, double click on the write operation and select the data object. The following table describes the columns projection properties that you configure for Kafka targets:
Property
Description
Column Name
The field in the target that the data object writes to.
This property is read-only.
Type
The native data type of the target.
This property is read-only.
Enable Column Projection
Indicates that you use a schema to publish the data to the target.
By default, the data is streamed in binary format. To change the streaming format, select this option and specify the schema format.
Schema Format
The format in which you stream data to the target. You can select one of the following formats:
  • XML
  • JSON
  • Flat
  • Avro
Use Schema
Specify the XSD schema for the XML format, acsample file for JSON, or .avsc file for Avro format.
For the Flat file format, configure the schema to associate a flat file to the Kafka target. When you provide a sample file, the Data Integration Service uses UTF-8 code page when writing the data.
Column Mapping
The mapping of data object to the target. Click
View
to see the mapping.
Project Column as Complex Data Type
Project columns as complex data type for hierarchical data.
