Explain advanced Change Data Capture (CDC) architecture in PHP ecosystems.

Change Data Capture captures database mutations in real time and streams them into distributed systems for synchronization, analytics, and event-driven architectures.

Traditional applications tightly couple transactional databases with downstream systems.

As systems scale, synchronous integration becomes fragile and inefficient.

CDC solves this by observing database transaction logs and streaming changes asynchronously.

Core CDC approaches:

Database triggers emit changes.

Problems:

Applications periodically scan changes.

Problems:

Reads database WAL/binlogs directly. Most scalable approach.…
