Today, if you are trying to harness the power of up-to-the-minute data, the challenge will be to capture and replicate changes seamlessly across datasets without compromising the performance or integrity of data. 

This is where the best CDC tools, which are modern software solutions, come into play. They are equipped with numerous mechanisms to detect and capture data change, which will ultimately enable you to be more dynamic and responsive.

In this blog, we will deep dive into the features, pros, cons, and pricing of the 7 best CDC tools so that you can make the best choice for your business.

What is Change Data Capture (CDC)?

Change Data Capture, which can also be referred to as CDC, is a process with respect to databases that identifies and tracks any changes that you made to your data. It can replicate this changed data and synchronize it in real-time across multiple systems. CDC propagates the 

updates you made effectively from source to target systems without the need to perform a full scan.

The general need for the CDC is to keep data consistent across a distributed environment for tasks such as data warehousing, business intelligence, and real-time analytics. Since CDC captures only changed data, it minimizes processing overhead and ensures real-time access to the most recent information for downstream systems.

Why do we need CDC Tools?

CDC (Change Data Capture) tools capture and replicate data changes from source databases to target systems in near real-time.

For example, in a retail company, implementing CDC tools was important for maintaining up-to-date inventory levels across multiple stores and online platforms. In this section, we will highlight the importance of CDC tools and why we need them.

  • Real-Time Data Replication: The CDC tools capture all changes made to data as they occur in source systems for near real-time replication into target systems. This will enable you to maintain up-to-date data of your organization across multiple systems.
  • Minimizes Processing Overhead: The best CDC tools help minimize full table scans or batch processing by capturing only the changed data. It minimizes resource consumption on source databases and improves overall system performance.
  • Disaster Recovery: CDC tools can support your business’s continuity since they facilitate rapid failover and recovery strategies.

Benefits of CDC Tools

As you are aware, CDC technologies gather information from several sources and import it into your data warehouse. Why, then, do you require this? For a variety of reasons, is the response.

  • Synchronizing replications: The act of tracking changes in a database and capturing them in real-time so that other systems may access the updated data is known as change data capture, or CDC. When real-time updates are required to keep a data warehouse or other downstream systems updated with changes in the source database, data warehousing or data integration scenarios are frequent use cases for CDC.
  • Low time consumption: The data warehouse’s data is always up to date as changes made to the transactional database are instantly recorded and transmitted there via CDC.
  • Minimized costs: You are proactively cutting expenses when you move data across WANs (Wide Area Networks) since CDC tools only deliver gradual updates.
  • Free resources for production: CDC technologies use logs to transport data, and log-based data transfers are incredibly effective ways to load data with the least amount of impact on production resources.
  • Reduced strain on the network: CDC technologies free up network capacity by facilitating gradual uploads. CDCs also provide protection against fraud.

What are the Challenges of using CDC Tools?

Database performance can be affected because CDC operations add more write operations to capture the changes.You can fine-tune configurations of CDC, like batch size and frequency, to lessen loads on source databases.
Ensuring consistency across a distributed system handling or resolving probable conflicts/discrepancies is challenging.You can implement timestamp-based conflict detection strategies or application-specific rules in the solution for conflict resolution.
The setup and maintenance of CDC configurations across heterogeneous systems can be a complex job and requires specialized knowledge.Use CDC tools that have a user-friendly interface and support automation in setup and configuration.
