Unzip gzip files in Azure Data factory

0 votes

I am wondering if it is possible to set up a source and sick in ADF that will unzip a gzip file and shows the extracted txt file. What happened is that the sink was incorrectly defined where both the source/sink had gzip compression.

So what ended up is that "fil1.gz" is now "file1.gz.gz".

This is how the file looks in Azure blob: enter image description here

This is how the file looks like in an S3 bucket (the end is cut off, but the end is "txt.gz"): enter image description here

I saw that in COPY there is Zipdeflate and deflate compression, but I get an error that it does not support this type of activity.

I created a sink in an ADF pipeline where I am trying to unzip it. In the datasource screen I used Zipdeflate, but it puts the file name with "deflate" extention, and not with the 'txt'.

How to unzip a GZIP file? here's some steps to be followed

  1. Save the.gzip file to your computer's desktop. If you downloaded a compressed file from a website, it may have been saved in the Downloads folder in your Documents or user directory.
  2. Start WinZip from the start menu or a desktop shortcut. Click File > Open to open the compressed file. Simply double-click on the file if your system has the compressed file extension associated with the WinZip programme.
  3. Select all of the files and folders contained within the compressed file. Alternatively, hold the CTRL key and left-click on the files or folders you want to open to multi-select them.
  4. In the WinZip toolbar, under the Unzip/Share tab, click 1-click Unzip and select Unzip to PC or Cloud.
  5. Choose the destination folder to place the extracting files and click "Unzip" button.
  6. Find your extracted files in the destination folder.
