How to set default Lakehouse in the notebook programmatically?

Hi All,

 

Here are my workspace setup:

 

WorkspaceFabric's ArtifactsGit branch folder
Fabric-Sandbox

notebook: landingtoBronze

lakehouse: Bronze

feature/bronze123

Fabric-Dev

notebook: landingtoBronze

lakehouse: Bronze

Dev

 

Problem:

 

Each time i updated the notebooks code to the Fabric-Dev workspace , i need to attach bronze lakehouse to "landingtoBronze" notebooks manually in the workspace so that it point to the right bronze lakehouse.  

Please note that each workspace has it own Bronze Lakehouse.

 

For example, I was working in the "landingtoBronze" notebook in my feature branch in the Fabric-sandbox workspace. during the notebook development, I attached the bronze lakehouse of the workspace as default lakehouse to the notebook.

once i had finished my notebook development, i created the pull request and merge the code from feature branch into dev branch.

 

while getting the code updated in the Fabric-Dev workspace, I can see the default bronze database is actually referring to the Fabric Sandbox workspace. 

 

Is it possible to attach a default lakehouse in the notebook programmactically?

 

Looking forward to hearing for any suggestion. it could be something that i am doing wrongly.

Hi @keataunooi 
Thanks for using Fabric Community.
To programmatically attach a lakehouse for a session level, you can use this below code in your notebook:

# Welcome to your new notebook
# Type here in the cell editor to add code!
%%configure
{
    "defaultLakehouse": {  # This overwrites the default lakehouse for current session
        "name": "your-lakehouse-name",
        #"id": "<(optional) lakehouse-id>",
        #"workspaceId": "<(optional) workspace-id-that-contains-the-lakehouse>" # Add workspace ID if it's from another workspace
    }
}


Hope this helps. Please let me know if you have any further questions.

For some people it worked but It didn't work for me. I got "UsageError: Line magic function `%%configure` not found."

Why?

Thanks

Thanks. just tested the code you provided. it works. 

I also figure out the default lakehouse of the notebook can be overriden by the pipeline deployment rules 

Create deployment rules for Fabric's Application lifecycle management (ALM) - Microsoft Fabric | Mic...

 

Thanks again!
