Hi, we have configured a gateway with a data source to AWS Athena. We are using Dataflow to connect to the AWS Athena dsn and then connecting to Dataflow in Power BI Desktop to build visuals. Initially, we found in Navigator that the "Table is Empty" . Per Microfoft's documentation, we found that this issue will arise because data has not been loaded to the table. When a dataflow is initially created, a refresh must occur to load data. When we selected "refresh now", it took about 30 minutes to load 302k rows from Athena. This seems fairly long considering the fact that we can query this same table in Athena in mere seconds.
Has anyone else encountered this same issue? Is this an expected behavior? Thank you very much.
