The majority of IT decision-makers, today, face delays in their business decisions due to slow data processing. As companies are collecting vast amounts of data, it is hampering the speed at which processors can run queries and extract the desired results. Change Data Capture (CDC) is the process that captures the changes made to a data storage medium like Database, Data Warehouse, etc. These changes usually refer to operations like data addition, deletion, updating, etc.
A straightforward way of Data Replication is to take a Database Dump that will export a Database and import it to a Data Warehouse/Lake, but this is not a scalable approach. Change Data Capture will capture just the changes made to the Database and apply those to the target Database.
CDC reduces the overhead and supports real-time analytics. It enables incremental loading and eliminates the need for bulk load updating.
However, before we learn about CDC tools, let’s learn a little about Change Data Capture and its importance.
Choosing the ideal CDC tool that perfectly meets your business requirements can be challenging, especially when a large variety of CDC tools and open source CDC tools are available in the market.
To simplify your search, here is a comprehensive list of the 7 best Change Data Capture tools you can choose from and easily start setting up your Data Replication.

Best CDC Tools 6: Debezium
Debezium is an open-source distributed platform for CDC built on top of Apache Kafka. It is scalable and can handle data of large volumes.
Debezium constantly monitors databases and enables applications to stream row-level changes to data in the order they were committed to the databases. Debezium monitors even when your apps are down so that they can start where they left off.
Debezium has support for MySQL servers, PostgreSQL servers, SQL servers, and MongoDB replica sets or sharded clusters. Debezium is distributed and fault-tolerant. Information loss is minimized because events are recorded across multiple machines.

Tacking Data Issues With CDC
It’s a good idea to consider the following before choosing the ideal CDC tool for your business:
- Problem solving: Are possible issues settled fast?
- Scale: Is the tool appropriate for every kind of database you use?
- Post-resolution: Is it simple to examine and customize the given solution?
- Support for database topology: Is the instrument adaptable? Is it capable of managing multiple master databases and replicas?
- More connection topologies and SSH tunnels: Is SSH connectivity available?
- Use cases: Can all use cases, tables, column data kinds, database types, and so forth be handled by the tool?
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.
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. This guarantees that reports and dashboards are consistently accurate and represent the most recent information while enabling analysts and other users to get the most recent data without having to wait for a batch process to complete.
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.
Choosing the Best CDC Tool
The implementation of appropriate change data capture methods can result in several benefits, including reduced network load, WAN data synchronization, expedited data replication procedures, and more.
An organization’s definition of a good change data-capturing tool may differ from another’s. Everything is dependent upon the data requirements and the data teams’ level of tool experience.
In this blog, you went through some of the best CDC tools to implement Change Data Capture. Hand-coding the CDC infrastructure comes with many challenges. It is difficult to manage and reusing code is complex. It also takes a lot of developer bandwidth. It is a lot more efficient to invest in an out-of-the-box tool like Hevo.
