I have a problem with my NestJS function,
I need to send 300 thousand records to my database, it is not a POST, it is a PATCH,
I have the function to know what data to update, but when uploading the data I found 2 problems:
1.- Sending all the data returned an error, saying that there is too much data to send.
2.- Make a for loop and put my query there, I tried it and it literally took days.
