DataflowGen2, which does not copy all the data...
Hello,
Thank you for your feedback.
By randomly removing 87/366 columns I have managed to read and write 32.152 lines on 70.037 lines.
By randomly removing 151/366 columns I have managed to read and write 54.922 lines on 70.037 lines.
By randomly removing 364/366 columns I have managed to read and write 70.037 lines on 70.037 lines.
So there seems to be a link between the number of columns and this problem.
These tests were done on an F2 capacity, I've tried on an F64 capacity, which doesn't solve the problem.
Do you have any idea what the problem is? It seems to come from DataflowGen2....
Thank in advance,
Vivien
Hello v-saisrao-msft ,
No the issue is not resolved. I have tested again, and it's the same.
Thank in advance,

Hi vivien57,
Please see the thread below, which outlines an issue similar to yours. In this case, the data preview in Dataflow Gen2 displays correctly, but some rows are missing in the Lakehouse after publishing.

Hello,
I am on vacation. I will do more tests when I get back in mid-August.
