The 7 Best CDC Tools (Change Data Capture)

on Data Integration, Data Processing, Data Replication • October 19th, 2020 • Write for Hevo

In the current scenario when data drives businesses, the majority of IT decision-makers face delays in their business decisions due to slow data processing. As companies are raking in vast amounts of data, it is hampering the speed at which the processors can run queries and extract the desired results. This in turn is affecting the decision-making process and companies are not able to achieve their targets and may even suffer huge losses.

Implementing ETL Pipeline architecture with the Database Replication property can speed up your data processing. This is because Database Replication creates the Analytics Database as a separate copy of the Production Database. This frees the Transaction Database from analytical queries while new data is saved in the Analytical Database to speed up the information retrieval process. Change Data Capture (CDC) is one of the most popular methods of carrying out this Data Replication process.

This article explores some of the best CDC tools that can amplify your business’s Data Processing speed.

Introduction to 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 DataWarehouse/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.

Change Data Capture (CDC) Tools

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 CDC 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 the project. Mainly due to the differences between Database Providers, Varying Record Formats, and even the inconvenience of accessing Log Records, CDC becomes a challenging task.
  • Regular Maintainance: Writing a script that can implement the CDC process is only the first step. 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.
