Custom live data source with MDX

Hi,

We have a in-memory DB that understands MDX and XMLA and we'd like to be able to connect to it from PowerBI in a "live" manner. E.g. DAX queries would be transformed into queries at some level in out data source, rather than being aggregated in PowerBI (we have tens of terrabytes of data potentially)

Is this possible? It seems very hard to write new data sources that undstand DAX and can translate it to efficient queries on the underlying data? In this sense it would work the same way as the SSAS connect I beleive

Thanks,

Ben
