Data Publishing Parameters (ttdpm5130m000)
Use this session to define the parameters for publishing to ION Messaging Service.
Buttons
These buttons are available:
- Check IMS Connection
- Checks if publishing to IMS with the parameters set is
possible.
This button is only valid for the IMS parameters.
- Publication Method
-
You can select one of these methods:
-
Data Lake Ingestion
The messages are published directly and not through ION. In this way it is not required to model a data flow within ION.
Note: If micro-batching is not enabled, Data Lake Ingestion is only used for Initial Load and the changes are published through ION Messaging Service (IMS).
-
ION Messaging Service
Data is published from LN to Data Lake through ION. You must model data flows in ION. Or, select this option when you have set up a data flow in ION that does not end in Data Lake.
Note: For Cloud environments, the connection point parameters are not displayed. These parameters are defined on system resources on Landlord level. -
