Ability to connect to AWS Athena would be ideal. It is an excellent platform to manage large data while you are in the exploratory stages.
'@Richard: PBI Gateway is only used in the context of hybrid connections between PBI online and on premises data sources (i.e. not for PaaS nor SaaS data sources) @Daniel: Interesting, but only relevant for connecting to Athena from PBI Desktop, so we're missing the most important part which is the ability to share these reports in PBI online @Yan: Most probably @MS: I would kindky urge you guys (as an ex-MSftee) to (re)prioritize the release and support of AWS data sources for PBI online if you don't want to loose new opportunities, as the Public Cloud is more and more becoming the place for (big) data to be hosted, and some tough competitors like Tableau and several others are supporting these for more than one year now (not to mention the newly released AWS QuickSight which is obviously supporting them all)
