Which statement best describes the batch job processing model in MuleSoft?

The batch job processing model in MuleSoft is designed to handle large volumes of records efficiently by dividing them into fixed-sized chunks. When a batch job is initiated, it processes these fixed blocks of records that are sent from the input payload. This allows for better resource management and performance optimization, as the system can handle each block sequentially while still maintaining an overarching structure for the job.

The approach of utilizing fixed blocks means that MuleSoft can maximize throughput while minimizing the complexity of managing individual records, making the batch processing model highly efficient for scenarios involving large datasets. By processing records in chunks, it can also facilitate error handling and logging for each batch, which is crucial in enterprise applications.
