Power BI Query Error: Timeout expired

This error indicates that you’ve pulled too much data according to your organization’s policies. Administrators incorporate this policy to avoid slowing down a different application or suite of applications that might also be using that database.

You can resolve this error by pulling fewer columns or rows from a single table. While you're writing SQL statements, it might be a common practice to include groupings and aggregations. You can also join multiple tables in a single SQL statement. Additionally, you can perform complicated subqueries and nested queries in a single statement. These complexities add to the query processing requirements of the relational system and can greatly elongate the time of implementation.

If you need the rows, columns, and complexity, consider taking small chunks of data and then bringing them back together by using Power Query. For instance, you can combine half the columns in one query and the other half in a different query. Power Query can merge those two queries back together after you're finished.

Azure built-in roles for tables

Azure RBAC provides built-in roles for authorizing access to table data using Microsoft Entra ID and OAuth. Built-in roles that provide permissions to tables in Azure Storage include: Storage Table Data Contributor: Use to grant read/write/delete permissions to Table storage resources. Storage Table Data Reader: Use to grant read-only permissions to Table storage resources. To learn how to assign an Azure built-in role to a security principal, see Assign an Azure role for access to table data. To learn how to list Azure RBAC roles and their permissions, see List Azure role definitions. For more information about how built-in roles are defined for Azure Storage, see Understand role definitions. For information about creating Azure custom roles, see Azure custom roles. Only roles explicitly defined for data access permit a security principal to access table data. Built-in roles such as Owner, Contributor, and Storage Account Contributor permit a security principal to manage a storage acc...

Select and configure an appropriate method for access to Azure Blobs

Azure Storage supports using Microsoft Entra ID to authorize requests to blob data. With Microsoft Entra ID, you can use Azure role-based access control (Azure RBAC) to grant permissions to a security principal, which may be a user, group, or application service principal. The security principal is authenticated by Microsoft Entra ID to return an OAuth 2.0 token. The token can then be used to authorize a request against the Blob service. Authorization with Microsoft Entra ID is available for all general-purpose and Blob storage accounts in all public regions and national clouds. Only storage accounts created with the Azure Resource Manager deployment model support Microsoft Entra authorization. For optimal security, Microsoft recommends using Microsoft Entra ID with managed identities to authorize requests against blob, queue, and table data, whenever possible. Authorization with Microsoft Entra ID and managed identities provides superior security and ease of use over Shared Key author...
