Cvent V2 midstream transformation in mappings

Use Cvent V2 Connector to interact with web service applications that support REST API. You can use Cvent V2 Connector midstream in a mapping to pass a single request to a web service application and process the response data.
Before you configure a midstream transformation, you must create a business service from the New > Components tab. You must select a Cvent V2 connection and an operation when you create a business service.
When you configure the midstream transformation, drag and drop the Web Service transformation, and then select the business service and the operation on the Web Service tab.
You can map the input fields from source file to elements in request structure on the Request Mapping tab.
You can view the response structure in the field mapping. When you map the elements from the response structure to the output fields, the Secure Agent creates the output groups, along with the primary and foreign keys for the field names.

Advanced midstream properties

The following table describes the advanced properties that you can configure for a midstream transformation:
Property
Description
Cache Size for Web Service Request (KB)
Memory available for the web service request.
Default is 100 KB. If the request is more than 100 KB, you can increase the cache size.
Cache Size for Web Service Response (KB)
Memory available for the web service response.
If the web service response contains many rows or columns, you might want to increase the cache size.
Default is 100 KB.
Allow Input Flush
Allows the Web Service transformation to create the request or response when all the data is available for a group.
If you do not enable this option, the Web Service transformation stores the data in memory and creates the request or response after it receives data for all the groups.
Configure the mapping so that the transformation receives data that is sorted by group.
Transaction Commit Control
Control to commit or roll back transactions based on the set of rows that pass through the transformation.
Use the transaction commit control if you have a large amount of data and you want to control how it is processed.
Transformation Scope
The method in which the mapping applies the transformation logic to incoming data.
Select one of the following transformation scopes from the list:
  • - All Input. Processes data from a source that is not real-time.
  • - Transaction. Processes data from a real-time source.
Default is All Input.
Optimize Transformation
Select to improve performance for processing records at run time.
Default is disabled.
