Open Table sources in mappings

When you configure a mapping in advanced mode to use an Open Table source, you can configure the source properties.
Specify the name and description of the Open Table source. Configure the source and advanced source properties for the Open Table object.
The following table describes the Open Table source properties that you can configure in a Source transformation:
Property
Description
Connection
Name of the source connection.
You can select an existing connection, create a new connection, or define parameter values for the source connection property.
If you want to overwrite the source connection properties at run time, select the Allow parameter to be overridden at run time option.
Source Type
Type of the Open Table source object.
You can choose from the following source types:
  • - Single Object. Select to specify a single Open Table object.
  • - Multiple Objects. This property does not apply to Source transformation.
  • - Parameter. Select to specify a parameter name. You can configure the source object in a mapping task associated with a mapping that uses this Source transformation.
Parameter
A parameter file where you define values that you want to update without the need to edit the task.
Select an existing parameter for the source object or click New Parameter to define a new parameter for the source object. The Parameter property appears only if you select parameter as the source type.
If you want to overwrite the parameter at run time, select the Allow parameter to be overridden at run time option.
When the task runs, the Secure Agent uses the parameters from the file that you specify in the advanced session properties.
Object
Source object for the mapping.
The following table describes the Open Table query options that you can configure in a Source transformation:
Property
Description
Filter
Filter value in a read operation. Click Configure to add conditions to filter records and reduce the number of rows that the Secure Agent reads from the source.
You can specify the following filter conditions:
  • - Not Parameterized. Use a basic filter to specify the object, field, operator, and value to select specific records.
  • - Completely Parameterized. Use a parameter to represent the field mapping.
  • - Advanced. Use an advanced filter to define a more complex filter condition that uses the Open Table query format.

The following table describes the Open Table source advanced properties that you can configure in a Source transformation:
Property
Description
Iceberg Spark Properties
The properties that you want to configure for the Iceberg tables.
Enter the properties in the following format:
<parameter name>=<parameter value>
If you enter more than one property, enter each property in a new line.
For example,
s3.access-points.<bucket name>=<S3 bucket ARN>
BucketRegion=<bucket-region-name>
Note: The S3 bucket ARN property is mandatory when the source and target are in different regions. For more information, see the Create the ARN for your AWS S3 bucket KB article.
Delta Spark Properties
The properties that you want to configure for the Delta Lake tables.
Enter the properties in the following format:
<parameter name>=<parameter value>
If you enter more than one property, enter each property in a new line.
For example,
BucketRegion=<bucket-region-name>
Tracing Level
Sets the amount of detail that appears in the log file.
You can choose terse, normal, verbose initialization, or verbose data. Default is normal.
