Informatica Cloud Mappings in Data Integration Hub
You use Informatica Cloud mappings in Data Integration Hub publications and subscriptions with automatic mappings.
In publication mappings, the publishing application is the source of the mapping and the Data Integration Hub publication repository is the target of the mapping. In subscription mappings, the Data Integration Hub publication repository is the source of the mapping and the subscribing application is the target of the mapping.
You can create a generic, parameterized mapping and use it for multiple publications and subscriptions. You can parameterize any element of the mapping, for example, source and target connections, field mappings, and transformations. The operator fills in the parameter values when they create the publication or subscription in the Data Integration Hub Operation Console.
Informatica Cloud Mappings Rules and Guidelines
When you develop Informatica Cloud mappings to use in Data Integration Hub publications and subscriptions with automatic mappings, consider the following rules and guidelines:
- •Do not run mappings that you create for Data Integration Hub from within Informatica Cloud. You must run Data Integration Hub mappings from Data Integration Hub by running the publication or the subscription to which the mapping is associated.
- •When you use the Data Integration Hub connection, if the mapping is not parametized, the target object in a publication mapping and the source object in a subscription mapping presents the list of topics defined in Data Integration Hub. The format of the list is TopicName.tableName.
- •If a mapping is parameterized, you can use it as both a publication mapping and a subscription mapping.
- •If a mapping is not parameterized, and you want to distinguish between publication mappings and subscription mappings, indicate the type of the mapping in the mapping name. For example, name a publication mapping Pub_<MappingName>, and name a subscription mapping Sub_<MappingName>.
- •You can add expression and filter transformations to the mapping.
- •If the mapping includes parameters, when the operator creates the publication or subscription, the parameters show in the Input Parameters tab of the publication or subscription wizard.
