I already found the source code and i modified it as needed.
How can I now get this info from Task that is created when Dataset is created?
Couldnt find anything like clearml.Dataset(id=id).get_size()

Im doing all of this because there isnt (or im not aware of) any good way understand what datasets are on workers

Hi @<1590514584836378624:profile|AmiableSeaturtle81> , not sure I understand this line

Is the order of --ids the same as returned rows?

Also, regarding the hash, I'd suggest opening a github feature request for this.
