Change Data Capture (CDC) is a key method for tracking and synchronizing database changes at the row level, crucial for disaster recovery. Apache SeaTunnel CDC enhances this process by offering two synchronization methods: Snapshot Read for historical data and Incremental Tracking for live changes. A highlight of SeaTunnel CDC is its lock-free snapshot synchronization, which avoids table locks common in other platforms. The architecture utilizes a splitEnumerator that partitions data for efficient parallel processing, allowing multiple readers to operate simultaneously and report progress effectively, resulting in timely event feedback.
Change Data Capture (CDC) is an essential technique for synchronizing data at the row level, allowing real-time updates and disaster recovery between primary and backup databases.
Apache SeaTunnel CDC provides two methodologies for data synchronization: Snapshot Read for historical data retrieval and Incremental Tracking for tracking incremental log changes.
The lock-free snapshot synchronization process in SeaTunnel CDC ensures that table locks are avoided during historical data synchronization, enhancing efficiency and system performance.
In SeaTunnel CDC, the splitEnumerator manages table data partitioning, distributing reading tasks among multiple readers to enable parallel processing and timely event feedback.
