What type of expression can be defined for records that did not fail during batch processing?

In batch processing within MuleSoft, an "accept expression" is essential for identifying which records should be processed successfully. This expression is used to specify the criteria for records that did not encounter any errors during processing. When a record meets the conditions of the accept expression, it indicates that the record can be safely accepted and further processed without issues.

The focus of the "accept expression" lies in its ability to filter out successful records, ensuring that only those records that meet the defined acceptance criteria progress through the batch job. This is crucial for efficient data handling and processing integrity, as it allows for clarity on which records were processed as expected.

In contrast, options like "reject expression," "ignore expression," and "default expression" have different functionalities. A reject expression is specifically for identifying records that should be excluded due to failures, while an ignore expression would typically indicate records that should be bypassed altogether without processing. A default expression, on the other hand, might apply an automatic default value if no other specific criteria are met, and is not related to the success of records during batch processing.

Understanding this distinction highlights the importance of the accept expression in the successful management and processing of batch records.
