The best way to fulfill orders during the peak season in an efficient manner is to create batches of orders and send each batch for processing when it gets full. This approach ensures that orders are processed promptly as soon as a batch is ready, which can optimize the workflow by reducing latency and keeping the processing pipelines continuously active. This method dynamically adapts to varying order volumes and does not rely on fixed schedule intervals, which might not cope efficiently with the variable load typical of peak seasons.
