In what scenario would the Bulk API not process a batch?

The Bulk API is designed to handle large volumes of records efficiently. However, there are specific conditions under which it may not process a batch. The selected scenario indicates that the Bulk API does not consider a batch unprocessable simply because less than 100 records fail.

The Bulk API has a tolerance for a certain number of errors within a batch; it will process the batch if the number of failed records does not exceed the pre-defined limit. This means that if only a small percentage of records fail—such as fewer than 100—then the Bulk API will still attempt to process the successful records. Consequently, a scenario where fewer than 100 records fail would not trigger a halt in processing the entire batch.

This ability to process successful records despite some failures is a significant feature of the Bulk API, allowing for efficient data operation and reducing the need for manual intervention or re-processing of entire batches when encountering minor issues.
