Not able to flatten big json file (almost 452 mb size) in adf. The file is having multiple json objects

Question

Hi,
I have created a big json file after combining many json responses from the API. Now the final file is almost 452 mbs in size and it is containing nested arrays. I tried using mapping dataflows but still not able to flatten it. can anyone help me out in this. I want to upload that file here for better understanding but can't upload due to size restriction.
