When is it most effective to use synchronous processing instead of Batch Processing?

Using synchronous processing is particularly effective for real-time data updates that require immediate feedback. This approach allows the system to provide prompt responses and ensures that any data changes are reflected in the system without delay. Synchronous processing is essential in scenarios where actions depend on the immediate results of previous actions, such as user-driven applications or systems that require interactive communication.

In contrast, batch processing is generally suited for tasks that involve handling large volumes of data over a longer time frame, such as bulk uploads or archival processes. These tasks do not require immediate feedback, making them perfect for batching since they can be processed at times that suit the system's workload and resource availability. Thus, when the requirement is immediate interaction and quick turnaround, synchronous processing becomes the clear choice.
