Running Report while AAZ tabular model is being refreshed

[simonliucan]

Hi there,

Quick question:

I have a dataset which uses live connection to Azure Analysis Service tabular model.

If my model is being refreshed and I run report based on this dataset:

    1. Do I get a blank report?

    2. Or do I get report with error message?

    3. Or do I get error indicating live connection error to AAS?

    4. Or anything else?

Thanks a lot,

Hi, @simonliucan 

Theoretically you will get the results of your run report before the refresh starts.

A scalable deployment for large query or processing workloads typically comes with expectations of high availability.

In a regular single-server deployment, processing and query workloads run concurrently, assuming system resources are sufficient for both activities. Analysis Services keeps existing data structures intact for query support while an updated version is being processed in the background. Having sufficient memory and disk space to handle temporary data structures is a hardware requirement that exists for all server modes, although each mode places different demands on system resources and comes with different levels of NUMA-awareness.

Here is the related document, hope it can help you.
