Hi,
We are just testing a new data gateway on an Azure VM, the data volume used in the current test data flow is much bigger than we'd tried previously (50 million records coming from an Azure SQL database). It seems that the whole dataset is spooling before its moved to the Power BI Service,taking a few hours, is this the expected behaviour? I'd previously thought spooling was for a situation where overflow occurred and data wasn't moving fast enough through the gateway, the machine spec is inline with those recommended in the documentation, though there is only one virtual NIC so perhaps throughput may be a bottleneck.
Appreciate any clarification/advice!
Thanks
