In the documentation at https://powerbi.microsoft.com/en-us/documentation/powerbi-refresh-data/
it is mentioned that for Live connections and Direct Query for data sources on cloud, gateway is not required and that data is refreshed automatically approximately every hour when there is no user interaction.
However it lists only Azure and Spark under the list of cloud data sources.
1. Is it also applicable for other cloud based data sources like Impala and will the data in dataset get refreshed as per the schedule?
2. If data source is in a private cloud, does the scheduled refresh work for live connection ?
It would be really helpful if Microsoft can list all data sources and support/ need for data refresh with/ without using on-premise gateway as it would help suggest the approach.
Thanks for the help.
