Best Practice for Lakehouse Table & View Deployments?

jochenj — Fri, 30 May 2025 12:00:29 GMT

i'm looking for best-practices how to track and deploy changes on LH-Managed Tables and LH-SQL-Views between workspaces.
How do you handle this task dynamically and with less-maintenance efforts?

Situation:

In Fabric WH and DB the git-integrations tracks all DB Objects like Tables,VIews,Procs... with this GIT integration we can use fabric deployment piplines to transfer changes from DEV (WorkspaceA) to PROD (WorkspaceB).

In Lakehouses we are missing the Object-Level tracking in GIT as stated here: Lakehouse deployment pipelines and git integration - Microsoft Fabric | Microsoft Learn

Important Only the Lakehouse container artifact is tracked in git in the current experience. Tables (Delta and non-Delta) and Folders in the Files section aren't tracked and versioned in git.

Solution Approaches:

Manually created/maintained notebooks
script-out all LH-Tables and LH-SQL-Views (which dependant on LH-Tables). Update that notebook on every change. Deploy this notebook regualary from DEV>PROD and then run this notebook manually
Dynamic Notebook
which dynamically reads all Table and View Definition, write it to a transportable file and then executes the notebook against target environments. Extracting the View-Definition can be done with INFORMATION_SCHEMA.VIEWs and i think LH-Table definitions should also be retrievable. Maybe us get_lakehouse_tables in sempy_labs library for the job?! (not tried)
Leverage Azure DevOps Pipelines
basically the same like approach 2 but orchestrate the process with DevOps Pipeline

Anyone with other options and/or practical experience what works best or maybe even also a working notebook solution?
I shouldn't be the first with this requirement?! Spoiler: My background is SQL-Datawarehounsing and not Lakehousing, so maybe my approach from Warehousing must be adpated to Lakehouse world?! We are implementing currenlty a lakehouse solution that has hundreds of LH-Tables and VIews. The solution relies on quiete extensive SQL Endpoint Views (much hof the transformation logic is inside views, this views act as input for a Notebook MERGE to silver-layer LH-Tables). Tracking all this tables/view with a manual notebook is not really feasible and time-intensive.. Side note: We moved to LH-Approach in hope that it is more capacity-efficent as our previous approach building a DWH based on Fabric Database, because we had to found out that the DB consumptions was eating our complete F64 capacity on data loads. But now challeging how to apply a working CI/CD Concept for LH

Hi @jochenj ,

Thanks for reaching out to the Microsoft fabric community forum.

Cosider this as a workaround and try it once. Create a notebook in your development workspace that automatically extracts metadata for all:

Lakehouse tables (Delta format)
SQL views (from the Lakehouse SQL endpoint)

semPy library use get_lakehouse_tables() to retrieve table definitions
SQL query SELECT * FROM INFORMATION_SCHEMA.VIEWS to get view definitions

You can serialize the output (e.g., as .json or .sql files) and store them in the Files section of your Lakehouse or in a dedicated folder within OneLake. This makes the metadata portable and ready for deployment to other environments.

If I misunderstand your needs or you still have problems on it, please feel free to let us know.  

Best Regards,
Menaka.
