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.
