Does the Bulk API reprocess records that have previously failed?

The Bulk API does not automatically reprocess records that have previously failed. When a batch processing operation is executed using the Bulk API, any records that encounter errors during the processing are not queued for reprocessing unless the user manually submits those records again. This means that the responsibility for addressing failures and attempting to reprocess any erroneous records falls on the user or the system integration logic implemented by the integration architect.

The Bulk API is designed for handling large volumes of data efficiently, but it does not provide an inherent retry mechanism for failed records after an initial processing attempt. It is essential for users to review the error messages provided in the API responses to understand the reasons for failures and to take necessary action to correct and resubmit any failed records if they wish to ensure successful processing.
