One or more attributes from the input payload on which the data should be grouped.
Columns To Merge
The attributes from the input payload whose data should be collapsed - the first non-null value will be used.
Before configuring the Transformation, please ensure that its input endpoint is connected to a parent Agent which will be sending data to it.
This endpoint is used to receive data from the parent Agent.
Each batch of events received from the parent Agent are first grouped by the specified attributes, the attributes to be merged are collapsed, and this payload is made available to this endpoint.
Attributes not in the group or merge selection will be removed from the output payload.
If errors are encountered during the execution of this Agent they will be published on this endpoint.
