Copy data for on-prem SQL server
Hi, does anyone have an idea of when the "Copy data" activity might work for on-prem data sources (in our case SQL Server)? I know we can use Gen2 dataflows for this - but they are very slow. Really ...
What sort of transfer rates ar you getting in gen2 dataflows? Mine just took an hour to load a 2gb table from On Prem SQL. Trying to work out if it's our environment or just how it is.
I'll send you some info once we get the firewalls opened. What I can say is this - if I look at Gen1 dataflow performance, it's nowhere even close to what the "COPY" utility is supposed to do. Based on this documentation ( https://learn.microsoft.com/en-us/azure/data-factory/copy-activity-performance ) I should be able to move our entire DW over in under an hour. That's orders of magnitude faster than what Gen1 dataflows feels like.
Hope this helps!
