Salesforce Bulk API supports both parallel mode and serial mode for processing data.

1. Parallel Mode:
• Description: In parallel mode, multiple batches of data are processed simultaneously. Each batch runs independently, potentially improving overall performance and reducing processing time.
• Use Cases: This mode is beneficial when dealing with large datasets or when there is a need for faster data processing. It allows for more efficient utilization of resources.
• Considerations: While parallel processing can be faster, it might consume more system resources. Careful consideration should be given to the total volume of data being processed and the system’s capacity.
2. Serial Mode:
• Description: In serial mode, batches are processed sequentially, one after the other. Each batch must complete before the next one starts. This ensures a more controlled and linear processing flow.
• Use Cases: Serial mode may be preferred when there are dependencies between batches, and it’s crucial to maintain a specific order of operations. It can also be useful for smaller datasets where parallel processing might not provide a significant performance advantage.
• Considerations: While serial processing may be more straightforward to manage, it may not be as efficient as parallel processing, especially for large datasets....
