In today’s fast-moving digital world, where data is super important, there’s something called Change Data Capture (CDC) that’s really helpful. CDC quietly does a big job in managing how data changes. In this blog, we’re going to explain what CDC is, talk about its different types, and look at the best ways to use it in managing data.
The Essence of CDC
CDC is like a watchful guard that keeps an eye on data, noticing every little change and making sure everything stays in sync across different areas. It’s not just about watching, though. CDC also makes sure that whenever data changes, those changes are recorded properly.
Unveiling the Tapestry of CDC
-
- Transactional CDC: Think of this as a meticulous writer carefully noting down every change that happens to data. It keeps track of every new piece of data, every update, and every deletion, making sure nothing gets missed.
-
- Log-based CDC: This is like a secret book where all the changes to data are written down. By reading these logs, CDC can understand how data is changing behind the scenes.
-
- Trigger-based CDC: Here, data changes are choreographed like a dance, with database triggers guiding the movements. It ensures that changes happen smoothly between different parts of a system.
-
- Streaming CDC: This type of CDC captures data changes as they happen in real-time, like listening to music as it’s being played. It helps keep everything in sync across different systems instantly.
A Glimpse into the Preferred Path
Among all the types of CDC, log-based CDC is considered the best. It’s efficient and can work in real-time, making it perfect for modern data systems.
Benefits of Log-based CDC:
-
- It doesn’t put too much pressure on the original databases, as it directly reads the transaction logs.
-
- Changes can be replicated in real-time or very quickly, which is great for keeping systems up to date.
-
- It keeps a detailed record of every change, making it easy to track what happened to the data.
-
- It can work with different types of databases, making it flexible for different setups.

CDC is like a conductor in the world of data, making sure everything runs smoothly. By using CDC effectively, businesses can make the most of their data and stay ahead in the digital world.
