I'm extremely new to salesforce and Bulk API. I've search for a possible solution for a couple of days, but haven't had any luck.
I have a CSV file with roughly 63 columns and roughly 1 million records. My goal is to upload this single CSV file to multiple sobjects. I'm currently able to upload to a single sobject with a CSV file that has the exact names as the sobject. I have found this link but I'm unable to find information on how to actually use this spec.csv file. Building it shouldn't be a problem. I need to break up this CSV file with 1 million records into multiple sobjects. A few columns need to go into Account and Contact and a few need to go into my custom objects as well. All in all, there are 6 sobjects this CSV file will populate. Can someone please direct me how this is possible?
Thank you in advance.
