Скачать или смотреть CDC vs CDF — Real-Time Data Changes Explained

In this video I break down Change Data Capture (CDC) and Change Data Feed (CDF) in plain language. You’ll see how CDC captures inserts, updates, and deletes from database commit/transaction logs, and how CDF (in table formats like Delta Lake and Apache Iceberg) exposes deltas so downstream pipelines can process changes incrementally.

What’s inside:

CDC basics: DML ops, commit logs, near-real-time streams

DDL/DML/DQL/DCL/TCL quick refresher

CDC vs CDF: where each fits in a lakehouse/Medallion architecture

Practical tools: Debezium, Airbyte, Azure Data Factory

Do you need a lakehouse? (CDC: no; CDF: typically yes)

If you’re building data pipelines or modernizing analytics, this will help you choose the right approach.
