Metadata from a referenced project

VNovitskiy — Fri, 15 Nov 2024 23:28:06 GMT

I have tried placing some of the common metadata, like connections and schemas, into a common project that can be referenced by other projects. This gives me a nice one-stop place to maintain metadata without the need to repeating it in every project. However, it seems that the Talend Studio doesn't know how to deal with metadata from a referenced project.

While I can drag and drop referenced metadata items on the canvas, the link between the created item and the reference repository doesn't work. For example, if I try to select edit schema and then update repository connection, I get an error that repository is not available. If I try to select a table schema from a referenced project metadata, nothing gets selected and the schema doesn't get updated. If I try to use a database connection with context, both of which are in a referenced project, the context data is not populated properly.

At this point I'm thinking that using metadata from a referenced project is not currently supported in the Talend Studio. Am I correct, or is there something I'm missing?

Thank you.

Using metadata from a referenced project is supported in Talend Studio, this is the basic function of reference project. Can you let us know which version of studio are you using?

I am using version R2021-09-7.3.1

Here are illustrations of the problems I'm having:

The above picture shows 2 problems - first is the double quotes around context variables for the connection. This doesn't happen if the metadata resides in the current project instead of a referenced one. Second problem is when I try to select a different schema from the repository, after I hit OK, nothing is changed.

In the above picture I am trying to update the existing schema from the repository, using Edit schema button. When I hit OK, I get this:

It seems that the update function failed because the schema came from a referenced project.

I didn't have any issues when working with metadata from current project.

Thank you.

@Vyacheslav Novitskiy, it sounds like a bug, please raise a ticket on Talend Support portal if you haven't submitted it yet. We need to install patch R2021-09 into studio 7.3.1 and make some testing.

Update:

Talend Support basically told me that it should work and provided links to limitations, permissions, and examples as they relate to the project references.

I ended up creating a new project, creating a common code reference in it, at which point it seems to work fine. I am thinking that the reason it is not working in the original project is because metadata was originally in it. After copying metadata to a common code project, I deleted it in the original project. Then I created a reference to the common code project, and none of the existing jobs or newly created jobs are able to use the referenced metadata.
