Data integration is essential for any competitive business. The ability to sync all your data from disparate sources powers better insights, analysis, and ultimately faster business decision-making. Change data capture (CDC) is one element of data integration that focuses on keeping data accurate with near real-time updates as soon as data within a data source changes. 

Our 5 key takeaways about the best change data capture tools:

  • Change data capture (CDC) is a data integration method that involves data streaming in increments to your data warehouse or lake to ensure accurate data collation, data replication, or even entire database replication.
  • Data transfer is fast because, in the CDC process, data replication occurs at the destination.
  • The best change data capture tools offer automation, monitoring, and other additional features.
  • Effective CDC creates complete business data that’s ready for analysis by tools such as BigQuery.
  • Data managers need to consider price, capability, features, and benefits before choosing a CDC tool.

We look at the best CDC tools available, their features, pros, cons, and more.

What Are Change Data Capture Tools?

Data integration tools find ways to connect to the business apps, SaaS, and databases that are vital for your day-to-day operations and longer-term analysis. One method for this is ETL (extract, transform, load) which involves connecting to sources via data pipelines, cleansing and transforming the data in a cloud-based staging area (for cloud-based ETL providers), and loading the information into your data warehouse, such as Snowflake or Amazon Redshift.

Another method is ELT or CDC: Extract, load, transform or change data capture. This method grabs the data from your source systems fast, updating every time a data transformation event occurs at the source. CDC tools are pieces of software or aspects of a data integration platform that empowers users to create data pipelines with ease, avoiding the need for manual coding.

Why Are CDC Tools So Important?

Data integration is more essential than ever as big data continues to get, well, even bigger. The world is on track to generate 181 zettabytes by 2025, so businesses must find ways to connect to and move data for real-time analytics. ETL is fantastic for full historical data loads but doing this every time you need your data warehouse updated is resource-heavy and time-consuming. CDC brings data across in smaller increments, which is quicker and uses less network provision. This cuts costs for businesses, and ensures data is as accurate as possible, not relying on manual pulls of data or even automation—it’s the change at the data source that prompts CDC tools to connect and collect new data.

CDC is also essential for avoiding latency. Because CDC updates your target system in incremental workloads, your systems won’t suddenly start lagging while heavy load queries get processed. Streaming data in real time can help with many emerging aspects of business technology, such as machine learning models that rely on huge data stores that are constantly shifting.

How Do CDC Tools Work?

CDC tools have the ability to detect row-level changes in relational database tables, such as “delete”, “update”, or “insert” events. These changes ultimately act as notifications for the CDC software to connect and draw the adjusted data from the source to the destination, and in some cases, any other system that relies on this data.

The change data capture process works as follows:

  • CDC tools extract any data that’s changed at the source.
  • Tools load data directly into the data destination for data ingestion.
  • The tool leverages the data destination's resources to ensure data is transformed in line with the destination format—this may involve standardizing, cleansing, sorting, and verifying different aspects of the data.

Because data only updates in the exact order it changes at the source, this avoids data duplication in your data lake or warehouse, maximizing the effectiveness of your available resources.

Common CDC Use Cases

You know that CDC tools grab data from a variety of sources and upload it into your data warehouse. But why do you need this? The answer is: for any number of reasons.

Change data capture (CDC) is a process used to track changes in a database and capture them in real-time, enabling other systems to consume this data as it is updated. A common use case for CDC is in data warehousing or data integration scenarios, where real-time updates are necessary to keep a data warehouse or other downstream systems up to date with changes in the source database.

For example, let's say that a company has a transactional database that is constantly being updated with new orders, customer information, and inventory changes. This database feeds into a data warehouse that is used for reporting and analytics. Without CDC, the data warehouse would have to periodically refresh its data from the transactional database, which could result in delays and outdated information.

By using CDC, changes to the transactional database are captured and sent to the data warehouse in real-time, ensuring that the data in the warehouse is always up-to-date. This allows analysts and other users to access the latest information without having to wait for a batch process to run, and it ensures that reports and dashboards are always accurate and reflect the latest information.
