What are the Challenges When Implementing Change Data Capture in MySQL? The tools used for capturing and collecting change events often faced failures and imposed additional strain on operational databases, leading to potential outages for both databases and applications under heavy load. However, configuring and managing CDC has historically been challenging. CDC has been widely used for extracting data from operational databases and loading it into data warehouses and data lakes for analytics, business intelligence, and reporting purposes. It allows the database to enforce ACID properties (Atomicity, Consistency, Isolation, Durability) and recover from failures.Īn essential aspect of CDC is the ability to transmit these captured change events to external systems for further processing or archival. This binlog plays a crucial role in ensuring the reliability and resilience of the database. In MySQL CDC, the changes are captured and stored in a transaction log known as a binlog. The captured changes are then delivered to external systems, typically for analytics purposes. These changes include additions, updates, deletions, and modifications to table schemas. It enables the monitoring, identification, and capture of changes made to the data stored in the database. What is change data capture (CDC) in MySQL?Ĭhange data capture (CDC) is a powerful data integration capability offered by MySQL and other major databases. You will also learn how to build a simple data pipeline to copy changed events from the MySQL to your data lake, automatically inserting, updating or deleting rows to match the original table. In this tutorial you will learn how to configure your MySQL database to enable CDC.
