Excuse me, everyone. I am a bit unclear about the concepts of TiFlash and TiCDC. Are there any articles that can help me understand these two components? Why doesn’t the official deployment documentation provide an installation guide for a cluster with both TiCDC and TiFlash components?

TiCDC and TiFlash are not related. One is an incremental data synchronization tool, and the other is a columnar storage engine. They do not affect each other and can be deployed together or separately scaled.
