# MariaDB Binlog/Replication API reference

The Binlog/Replication API enables client applications to connect to a MariaDB server and stream its binary log as replication events. When binary logging is enabled, the log records all data manipulation and definition changes.

This API is particularly useful for building change‑data capture (CDC) pipelines, custom replication consumers, and auditing tools.
