Creating zip file in notebook

[VenDaFabricator]

I got bunch of .delta table which in need to save as .json and zip them to supply it thrid party tool for futher processing.

I was able to get all .delta tables into .json files, but getting erro when zipping them.

My .json files are in folder 

'Files/temp/consolidated/'

Now i want them to zip them all into 'sample.zip' ... he is my code, not sure what am doing wrong zipf.write can find the json_file_path though is right.  Any clues?? or is there different way to do it?

with zipfile.ZipFile('sample.zip', 'w') as zipf:
    for f in filenames:
        json_file_path = f"Files/temp/consolidated/{f}"
        print (json_file_path)
        zipf.write(json_file_path,arcname=f)

Microsoft Fabric Context: The Fabric environment uses a virtual file system, which doesn’t provide direct file path access as in traditional file systems.

zipfile.ZipFile.write Limitation: This method expects a direct file path, which isn't available for Fabric paths.

Why not use a copy command in a pipeline, you can iterate over all the table you want.

Delta Table as you source

OneLake File as your destination json file type, set the compression type to .zip

Hi @VenDaFabricator 

Maybe you can mount the lakehouse through the Microsoft Spark Utilities package? Mount would allow you to use the local file API to access data under the mount point as if it's stored in the local file system.

Access files under the mount point via local path 

I haven't used it to create zip files, you can give it a try.

not sure what am doing wrong

It's pretty clear that what you are trying to do is not supported. Don't use zipFile - use its in-memory equivalent, whatever that is.

Thanks lbendlin for the reply, do you got any sample code using in-memory to do this zipping for files or any links.

[lbendlin]

BytesIO , I guess.

python create zip file in memory at DuckDuckGo

Thanks @lbendlin 👍 ... will give a try and see how it goes.  👍
