I'm evaluating Power BI for my 3,000-person company. I'll need to get data from MongoDB and Elasticsearch, which Power BI doesn't currently support. Let's say I followed this guy's advice and wrote a connector from Power BI Desktop to Elasticsearch. I then upload the workbook to Power BI on the web and tell it to refresh itself every week. To do the refresh:
Won't Power BI on the web need an Azure gateway into Elasticsearch?
Could the desktop connector I wrote serve?
If not, what else would I need to create?
Roughly how many hours would that take?
In general, it seems like building a desktop connector is not the end of what's needed.
