TiCDC (TiDB Change Data Capture) is a tool used to capture and output data changes on TiDB/TiKV clusters. It can serve as an incremental data synchronization tool for TiDB, synchronizing incremental data from the TiDB cluster to downstream databases, and also provides an open data protocol to support publishing data to third-party systems.
In response to the community’s call, the TiCDC source code interpretation series continues. This issue is the 8th in the series and will start on March 16th (Thursday) at 20:00.
If you have any questions about this issue, feel free to leave a comment in this thread. We will invite the guest speaker to answer them during the live broadcast.

This Issue’s Topic
TiCDC Source Code Interpretation #8: Implementation Principles and Performance Optimization of TiCDC MySQL Sink
Key Points of Sharing
The Sink module in TiCDC pulls sorted row changes from the sorter and synchronizes the data to downstream according to a specific protocol. This issue mainly introduces the implementation principles of the MySQL sink in the Sink module, focusing on the following issues:
- Transaction handling and conflict detection mechanism of MySQL sink
- How MySQL sink improves the performance of writing to downstream
- How MySQL sink solves performance bottlenecks in cross-region replication and high-latency network scenarios
- Some optimization directions for MySQL sink in the future
