How To create Batch API in Drupal

Batch processing involves executing a series of jobs in a site without manual intervention each on a set or “batch” of inputs, rather than a single input. Batch operation in Drupal APIs is primarily designed to integrate nicely with the form API workflow, but can also used by non-form API scripts.

1. You can break long tasks into smaller batches , preventing max_execution_times error.
2. You can give the visitors ( or more likely administration or developer ) some feedback.
