Bulk API Ingest

With Bulk API, you can insert, update, or upsert large data sets into your Salesforce org. Prepare a CSV, XML, or JSON file representation of the data you want to upload, create a job, upload job data, and let Salesforce take care of the rest.

Bulk API ingest limits are described in Bulk API and Bulk API 2.0 Limits and Allocations in the Salesforce Developer Limits and Allocations Quick Reference
