Increase In Copy Activity CU Usage
Hi Dinesh - Thanks for the suggestions. I checked them all. This was an issue with every copy activity - and data movement was the operation where CU increase occurred. Our gateway is up to date. The pipeline has not changed.
Possible Good News: This morning, the CU usage returned to normal without any intervention or changes on our part. This makes me wonder if there was a bug. I will continue to watch through the week to make sure the issue doesn't recur.
Hi. Expecriencing the exact same issue since Saturday ~7.00am EEST. This seem to affect the minimum volume pipelines. Unbearable situation in production environments.
Thanks for chiming in. I was afraid it was just us. Have you received any insight into what is causing this?

Did you check the duration of the Copy Activity (Data Movement) in the Capacity Metrics App or the Data Pipeline run history?
Under normal conditions, the CU cost is 360 CU (s) per started minute.
If it runs for 1 second it will cost 360 CU (s), if it runs for 1 min 1 sec it will cost 720 CU (s) and if it runs for 2 min 1 sec it will cost 1080 CU (s).
Thanks for the question. I did check all of the run times. Almost all of the processes completed in less than a minute but the data movement charge was 1080. For the few that completed in more than 1 minute but less than 2, the cost was 1440.
This was an issue for us on Sunday and Monday. It mysteriously fixed itself on Tuesday morning to align with exactly what you've described above. (We didn't change anything.)
