[All Databricks Certified Data Engineer Professional Questions]

A data engineer needs to capture pipeline settings from an existing in the workspace, and use them to create and version a JSON file to create a new pipeline.

Which command should the data engineer enter in a web terminal configured with the Databricks CLI?

AUse the get command to capture the settings for the existing pipeline; remove the pipeline_id and rename the pipeline; use this in a create command

BStop the existing pipeline; use the returned settings in a reset command

CUse the alone command to create a copy of an existing pipeline; use the get JSON command to get the pipeline definition; save this to git

DUse list pipelines to get the specs for all pipelines; get the pipeline spec from the return results parse and use this to create a pipeline

Show Suggested Answer

Suggested Answer: A

The Databricks CLI provides a way to automate interactions with Databricks services. When dealing with pipelines, you can use the databricks pipelines get --pipeline-id command to capture the settings of an existing pipeline in JSON format. This JSON can then be modified by removing the pipeline_id to prevent conflicts and renaming the pipeline to create a new pipeline. The modified JSON file can then be used with the databricks pipelines create command to create a new pipeline with those settings.

Not sure about option D, seems a bit complicated.

Wait, can you really just rename the pipeline like that?

I thought we could use the alone command to create a copy, but that doesn't sound right now. I should have reviewed the JSON commands more thoroughly.

I feel like option D might be the right choice since it mentions getting specs for all pipelines, but I’m a bit confused about how to parse the results.

I remember practicing a similar question where we had to retrieve pipeline settings, but I can't recall if we used a reset command or something else.

I think we need to use the get command to capture the settings, but I'm not sure if we have to rename the pipeline or just modify it directly.

Option D looks interesting, but I'm not sure how reliable it would be to parse the list of pipelines to get the specs. Seems like there could be some edge cases there. I'd probably stick with A or C to be on the safe side.

I think option C is the way to go. Using the "alone" command to create a copy of the existing pipeline, then getting the JSON definition and saving it to git seems like a good way to version the pipeline settings.

Hmm, I'm a bit confused by the question. Do we need to stop the existing pipeline first before creating a new one? Option B mentions stopping the existing pipeline, but I'm not sure if that's necessary.

This seems straightforward - I'd go with option A. Capture the settings for the existing pipeline, remove the pipeline ID, and use that to create a new pipeline.

I think one advantage is that they let different projects use different versions of the same libraries without conflicts.

D) that's a clever approach, but it seems a bit overkill. Why not just use the get command like in A)? Less steps, you know?

C) is interesting, but I don't think creating a copy of an existing pipeline is what the question is asking for. We need to create a new pipeline based on the existing one.
