I have a 12 nodes cluster of D12v2 (4 cores, 28GB, 200GB) images. We're copying about 100GB from the cluster's local HDFS to ADLS or WASB. I believe Blob Storage is being capped at 1000 IOPS per account, I was wondering what to expect copying to ADLS with a conservative number of mappers (36-48).
Did you figure out the difference? I am also interested in the difference between ADLS and Blob storage in terms of performance.
