Drupal Queued Batch Processing for Large Volume Transactions

There are occasions when transactions processing becomes a challenge due to the dataset being large in size, large in record volume, or both. This can result in the processing failing at any point before its completion. There is a silver lining in this dark cloud, and it is queued batch processing. It is likely that you are familiar with batch processing – executing activities in the background, with cron processing being the common example. Queued batch processing facilitates processing the batch in smaller chunks, thus avoiding the pitfalls that might be experienced, otherwise.
