CDC Tools

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 one of the most popular methods of carrying out Data Replication process, that can speed up your data processing. In this article, we will explore the best CDC tools that can increase your business’s data processing speed.

However, before we learn about CDC tools, let’s learn a little about Change Data Capture and its importance.

What is Change Data Capture (CDC)?

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.

Why Do We Need CDC?

CDC offers several advantages to your organization:

  1. Faster Decisions: CDC enables faster decision-making by replicating data in real-time with zero-downtime database migrations.
  2. Synchronous Replication: CDC can be used for real-time data replication since it uses transaction logs to copy databases. CDC enables streaming ETL pipelines and allows for real-time analytics.
  3. Free Production Resources: CDCs transfer data from a production database to an analytic database, via logs. Log-based data transfer is a highly efficient approach for limiting impact on production resources when loading new data.
  4. Reduced Costs: CDCs can move data across a wide area network (WAN) and can optimize your costs by sending only incremental changes.
  5. Decreased Network Burden: With incremental uploads, CDC frees up your network bandwidth. It also offers fraud protection, and data synchronization across geographically distributed systems.

Why Do We Need a CDC Tool?

Now as you have understood the importance of Change Data Capture (CDC), the question arises, if one can develop an in-house CDC process, why does one need Change Data Capture tools?

Following limitations of developing a CDC solution will help you comprehend the necessity of using the best CDC tools for your business:

  • Complex Task: CDC Data Replication is not a one-time easy to do project. CDC becomes a challenging task mainly due to the differences between database providers, varying record formats, and even the inconvenience of accessing log records.
  • Regular Maintenance: The first step is to write a script that can implement the CDC process. When your database and log patterns change, you also need to maintain a customized solution that can map these changes regularly. This implies a lot of time and resources will be used up in maintaining your in-house CDC process.
  • Overburdening: Developers in companies usually already face the burden of public queries. The added work of building your own CDC solution will affect your existing revenue-generating projects as the developers’ time will be divided now.

Best CDC Tools

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.
