Storage need in Microsoft Fabric

[webchris]

Dear all

I have the following questions:

I remember that when one deletes data from a table with a delete statement instead of a truncate, that could lead to storage consumption issues. 

Now that Microsoft Fabric does not support "truncate table", I wonder whether my storage consumption will increase when I use "delete from" instead.

Thanks for feedback!

You can run VACUUM on your lakehouse tables to hard delete data. There's a default retention period of 7 days in the delta logs but you can reconfigure this to be more aggressive.

I believe Warehouse tables also have a default retention period of 7 days too
