Is there a way to ZIP files using 7z format in Azure Data Factory?

Question

I'm in the process of migrating an SSIS package to Azure Data Factory Pipeline, one of the things it does is ZIPs a large file (around 4gigs) to .7z format. I need to be able to duplicate this function within Azure Data Factory.

I noticed, in the DelimitedText DataSet, that it's not an available option on the 'Compression type' dropdown. Is there a way to use this format? Has anyone else been able to do this?

If 7zip is not an option, does anyone have any suggestions that would be comparable? I checked out .zip and the file is still to big.

I've searched everywhere and I couldn't find an answer for this. Everything revolved around unzipping. I need to ZIP a file to this format.

Thank you.

You can use ZipDeflate(.zip) for the .7z format file like below.

These are my source files in a container.

Create binary datasets for both source and target. In the source dataset give the path till the required folder. Here I have given the path till the container inputdata.

In the target, give your path and compression type like below.

Execute the copy activity and you will see the required file in the target with less size.
