Bulk API
Bulk API is the predecessor to the current Bulk API 2.0. Although Bulk API gives you
more fine-grained control over the specifics of jobs and batches, its work-flow is more complex
than Bulk API 2.0. If the feature set and limits are a unique match to your project requirements,
use Bulk API.
