Should I create Azure storage & Metastore in the same region?

Question

I am going to create a Metasore following the documentation.

 

Regarding the storage account, I don't understand if it should be in the same region as Metastore.

 

From documentation:

 

You can create no more than one metastore per region. It is recommended that you use the same region for your metastore and storage container.

Is it a recommendation or a must?

 

Another part of the documentation:

@Mohammad Saber Thanks for the question and using MS Q&A platform.
The summary of the both the statement are (Workspace, Metastore and storage account) account should be in same region.

Example: If you Azure Databricks workspace created in "East US" , then the storage account should be in same region - so that you can configure the metastore using the storage account which you created earlier.
Statement1: You can create no more than one metastore per region. It is recommended that you use the same region for your metastore and storage container. - This clearly says that you cannot create more than one metastore per region which mean you can only one metastore per region.

Statement2: This must be in the same region as the workspaces you want to use to access the data. Make sure that this matches the region of the storage container you created earlier. - if your Workspace & Metastore in East US you should choose storage account be East US only.

Example: If you create a metastore in with storage account in East US - you cannot create one more metastore in East US region - it's limited to one metastore & Storage account per region.
