Talend Data Mapper - Invoking mappings with different configurations

Morpheus — Sat, 16 Nov 2024 07:45:16 GMT

Hi Guys,

I have followed the tHMap examples on the help page and I got some understanding on how the mappings developed from TDM can be invoked within a Talend standard job. As per to the examples below is possible.

Using Talend data mapper metadata to another structure created by Talend data mapper (tdm to tdm): In this case, we use the below component configuration.
tFileInputRaw --->tHMap ---> tFileOutputRaw
Using Data Integration metadata to another structure based on Talend data integration metadata (di to di): In this case, we use the below component configuration.
tFileInputDelimited --->tHMap ---> tFileOutputDelimited

I am wondering if it is possible to invoke a data mapper job with cross combination of above:

e.g.

Using Talend Data Mapper metadata to another structure based on the Talend Data Integration metadata (tdm to di) or vice-versa. If there is no direct way, do we need to do it as two different jobs?

I tried to do that, however, noticed that the "Write Output As Data Integration Columns" option is not coming in the tHMap component window under basic settings. It is coming only if DI to DI mapping layouts are selected.

I agree that the data integration metadata to talend data mapper metadata type is covered by the "Scenario 3: Transforming from a Data Integration schema to a complex content schema". How about the doing it the other way (i.e. TDM to DI with "Write Output As Data Integration Columns" option enabled)?

tFileInputRaw --->tHMap ---> tFileOutputDelimited
