What is a characteristic of the Force.com Bulk API?

The Force.com Bulk API is specifically designed to handle large volumes of data efficiently. Its primary characteristic is that it improves throughput for loading large amounts of data by allowing asynchronous processing. This means that it minimizes the amount of time needed to load large datasets by batching the data into smaller chunks, which the system processes in parallel. This capability is crucial for data-intensive applications where performance is a priority, enabling users to import and export millions of records without overloading the system.

The other options provide characteristics that don't align with the core functionality of the Bulk API. For instance, it is not meant for real-time processing; that would be more suited to the standard REST or SOAP APIs. While the Bulk API is stateless, its monitoring features are robust for a bulk system, allowing users to check the progress of their jobs. Additionally, the Bulk API is designed for inserting, updating, and deleting records, not just for data retrieval. This functionality enhances its utility in extensive data migration and ETL processes.
