Hi Team,
Environment: Centos 7, 4 Nodes, Dremio 2.1, SQL Server Data Source
At a Data Source level, the option “Never Refresh” under the Refresh Policy does not seem to be working. To replicate the issue just select it and save, next time you reopen the dialog section you will notice that it is NOT selected (from a GUI perspective). From a backend perspective, I did notice that reflections seem to keep refreshing on the background (unit I selected the option again at a dataset level).
