## TL;DR

Debezium CDC turns database changes into event streams that data agents can use for freshness, lineage, and incremental processing.

## Core Explanation

Batch pipelines often lag behind source systems. Change data capture listens to database changes and emits events as rows are inserted, updated, or deleted. This gives downstream systems a way to update indexes, caches, feature stores, and data products without full reloads.

For agents, CDC evidence matters because it explains why a dataset changed and whether a retrieval or analytics index is current. The agent should inspect connector status, offsets, schema changes, and snapshot state before trusting pipeline freshness.
