In plain words: A Metadata-Driven Deletion Batch is a reusable Batch Apex job that purges outdated records based on configuration rules stored in Custom Metadata Types (CMDT) . Instead of editing and deploying code whenever you need to clean up an object, administrators simply update metadata fields (such as target object name, date range, or active status), and the batch automatically executes the correct SOQL query. Maintaining data hygiene and keeping storage consumption within platform limits often requires automated record cleanup. However, hardcoding object names, date filters, or WHERE clauses directly inside Apex classes creates ongoing maintenance debt. Every requirement change forces developers to edit code, write new unit tests, and coordinate production deployments. Coupling Batch Apex with Custom Metadata Types creates a declarative engine that lets teams manage data retention policies without touching code.
