Which action is NOT a characteristic of Bulk API processing?

Bulk API processing is specifically designed to manage and handle large volumes of records efficiently by breaking the data into manageable batches. Therefore, handling large volumes of records is a fundamental characteristic of the Bulk API.

Batch processing of data is also a crucial aspect, as Bulk API allows for the submission of multiple records in a single API request, optimizing the processing time and resource usage in Salesforce.

Resending failed records after defined attempts is a feature that enhances the reliability of the Bulk API. It ensures that if there are any issues with specific records during processing, they can be automatically attempted again based on pre-defined criteria, ensuring data integrity and consistency.

Immediate processing, however, does not align with the characteristics of Bulk API. Bulk API processes records asynchronously rather than instantly. This means that when data is sent through the Bulk API, it may take some time before the records are actually processed and the user receives updates about the success or failure of those records. Immediate processing is more descriptive of the REST API or the SOAP API, which handle real-time transactions and provide instant feedback.
