What should be done after all batches are sent when using the Bulk API?

When using the Bulk API in Salesforce, it is essential to retrieve batch results after all batches are sent. This step is crucial because it provides feedback on the outcome of the batch processing, including which records were successfully processed, which may have encountered errors, and the specific details of those errors.

Retrieving batch results allows integration developers to handle any issues that might have arisen during the data loading process. This can include tracking records that failed during insertion, ensuring data integrity, and taking appropriate action for any errors encountered. Overall, this step is vital for monitoring the success of the data upload process and for making necessary adjustments to data or retrying failed records.

The other choices focus on actions that are not immediately necessary or relevant to the workflow after sending batches. Logging out of Salesforce does not contribute to the data processing workflow, deleting batch records may not be applicable if you still need to analyze the results, and creating a new bulk job would only be the next step after confirming the success of the current job.
