The Data Map collection limit has been increased from 400 to 1000
We are pleased to announce the general availability of the "1000 collections" in Data Map.
Collections in the Data Map serve as a logical construct designed to organize assets and data sources within a customer’s data estate by business units.
Additionally, collections are utilized to manage access within Microsoft Purview’s unified catalog.
The increase in collection limit from 400 to 1000 will offer enterprise customers greater flexibility and control over data source segregation in response to evolving business requirements.
Even though the limit has been increased, we recommend following the best practice guide shared here.
