tHMap (Data Mapper) version management for Maps and Structures

SMR040 — Fri, 15 Nov 2024 22:23:20 GMT

Hi community,

The Data Mapper is a very powerful product and because of that I use it very often. But one thing I could not find any documentation about is the versioning for Maps and Structures. Of course I can duplicate existing Maps etc and add _0.1 for example but this will create a huge list eventually. Also I understand that when you use a source file like with APIs you can use OAS spec and keep versions on the input side.

But what I am looking for is to version the Maps and Structures. The reason for that is because that for every new version of a job the same version of the Map is used. So it is not possible to revert changes when going back to a previous version of the job.

Thanks!

While the file versioning is still supported in Talend Studio, we would advise using Git versioning moving forward.

thanks for your response. How would you see that with Maps and Structures? For example how can I make a distinction in the versions of mapping and relate that version with a specific job version?

Would help if you gave a practical example.

Thanks

@Richard Hall could you guide me some more on how to use GIT versioning with Data Mapper structures and maps?
