The MySQL Change Data Capture (CDC) technique allows users to track and capture changes in data, enabling real-time processing of events and improving data management strategies. By tracking changes in binary log files, CDC can capture insertions, updates, and deletions, allowing for the use of changes in various purposes such as data replication, data warehousing, and real-time analytics. The implementation of CDC in MySQL can be done through several methods, including trigger-based CDC, query-based CDC, and BinLog for CDC, each with its advantages and disadvantages. Additionally, tools like CData Sync leverage CDC configuration to replicate data efficiently, offering flexible and precise data management capabilities.
