1400 Compatibility Level in Azure Analysis Services

  • 项目

We are excited to announce the public preview of the 1400 compatibility level for tabular models in Azure Analysis Services! This brings a host of new connectivity and modeling features for comprehensive, enterprise-scale analytic solutions delivering actionable insights. The 1400 compatibility level will also be available in SQL Server 2017 Analysis Services, ensuring a symmetric modeling capability across on-premises and the cloud.

Here are just some highlights of the new features available to 1400 models.

  • New infrastructure for data connectivity and ingestion into tabular models with support for TOM APIs and TMSL scripting. This enables:
    • Support for additional data sources, such as Azure Blob storage. Additional data sources are planned soon.
    • Data transformation and data mashup capabilities.
  • Support for BI tools such as Microsoft Excel enable drill-down to detailed data from an aggregated report. For example, when end-users view total sales for a region and month, they can view the associated order details.
  • Object-level security to secure table and column names in addition to the data within them.
  • Enhanced support for ragged hierarchies such as organizational charts and chart of accounts.
  • Various other improvements for performance, monitoring and consistency with the Power BI modeling experience.

Please see this post on the Azure blog for more information.

      Parv, at the moment only cloud-based sources are supported for Azure Analysis Services, but a new gateway version is going to be released very soon to make on-prem sources available.

    Is there a good source for documentation on the Get Data integration? The feature set is very different from Power BI's Query Editor, is there a road map to integrate Merge and Append, for example?
