Number of mashup engine containers

[l2aFa]

Hello everybody,

After the January gateway update (https://powerbi.microsoft.com/en-us/blog/on-premises-data-gateway-january-update-is-now-available/) and the possibility of controlling the number of mashup engine containers I have trouble figuring what applies to my circumstances, which are:

- I currently develop reports against SSAS tabular models through live connection.

-These models are deployed in an Azure machine; let's call it A.

-My on-premises data gateway is installed on another Azure machine which only holds an SSIS instance; lets call it B.

-My published Power BI reports connect to A through B gateway.

My question is this: if I tweak the number of mashup engine containers, will it affect the resources of A or B? B is the one with the gateway installed, but it will be A resources the ones used to query the different models and answer the viewer's demands.

Also, A and B don't have the same amount of cores, so I don't know which number I must employ as guidance to establish the MashupDefaultPoolContainerMaxCount value as the article says.

Thank you very much in advance!

@l2aFa,

When you tweak the number of mashup engine containers, it will require B’s resources and affect your machine B’ s performance. In your scenario, if you only have live datasets, the On-Premise Gateway will act as in a pass along mode, passing the data to the source, getting the results and passing it back to the Power BI Service, the query will be executed at the source side(Machine A). In this case, I don’t think you have to change the “MashupDefalutPoolConainerMaxCount” setting as there are no queries running or data model at gateway side.

However, if you persist to change number of mashup engine containers , as the blog says, a recommended ceiling for the maximum number of containers you can use is roughly twice the number of cores in your local machine(B) processor.

Thank you very much for your answer Lydia, I will have this in mind.
