When you have a data warehouse execution that uses solely on-demand data sources, you might come across a rather odd gantt-chart in the execution log:
The table has a large blank space because of the use of on-demand data sources. If I am not mistaken, the blank space represents the ODX transfers that are initiated as a result of the on-demand setting.
What is the best way to monitor your DWH performance in this setting? The gantt-chart is a great tool to identify possible fixes in order to reduce the reload time of your DWH. In this case it becomes rather complicate to use it for that purpose.
