PowerBI Datamart data size/volumes



As per the MS Doc- Datamarts currently officially support data volumes of up to 100 GB.


1. So, Is it per datamart 100 GB or per workspace? As we can have multiple datamart in our workspace, suppose I have 5 datamarts so the datasize, it's going to support upto 500 gb or collectively 100 gb only?

2. Can we increase the databse size?

HI @nik-1854,

#1, I think the size limit should mean the per 'data model' limitation in the PPU license instead of the workspace. I'd like to suggest you take a look at the following link that mentions the data storage limitations:

Manage data storage in your workspaces - Power BI | Microsoft Docs

Power BI Premium Per User - Power BI | Microsoft Docs

#2, Did you mean to increase the dataset size limit? If that is the case, you can enable the 'larger dataset' storage option or assign your content to a common premium capacity to increase the size limit.

Hi Xiaoxin Sheng,

Is this true in case of Datamart as well?
