Hey All, Question about the data source and PDM/LDM. We are working on our development process of promoting our LDM between environments (instances of GD for dev,qa, etc.). I just imported our LDM into our QA environment and it failed to map to the PDM because the data source needed to be refreshed. (I fixed this issue by refreshing the data model and then re-importing the LDM through the API). Is there some API or process to refresh the data source/PDM? It happens quite a bit where we change/update the actual data model and need the PDM to be refreshed to get the new changes. If not understand its something we'll need to do as part of the publish of our LDM (validate the mapping)

Hi Steve, Definitely, you can use the bellow API to scan/refresh your database/PDM: https://www.gooddata.com/developers/cloud-native/doc/cloud/api-and-sdk/api/api_reference_all/#operation/scanDataSource

That will force a refresh of the datasource/PDM?

the refresh from the UI triggers the same API endpoints from the documentation:

Ah, ok seeing what the client is doing: Calls: scan, then does a put on the physicalModel

@Steve Fox Let me double-check this internally.

Hi Steve, Please let me step in here. The endpoints are still valid now, but the PDM will be deprecated soon. You can follow our Release Notes to stay up to date.

Sure, my question is what is the replacement?

Hi Steve, basically the plan is to extend the LDM with the required information, so it will be no longer needed to have it separated. The rollout will be done in a way that there will be a transition period when both of these ways (PDM vs extended LDM) will work and also the LDM will extend itself automatically with the information from existing PDM. This should be described in the upcoming release notes once the change is made. I'll be happy to answer any further questions.

Ok, good to know
