Hello everyone, I am currently studying the principles of TiCDC. I have a basic understanding of handling CDC events, but the blog does not provide a detailed description of the gRPC requests to the CDC module. For example, what parameters are needed for this gRPC request, the meaning of each parameter, the possible values for each parameter, etc. Is there a comprehensive gRPC request documentation for the CDC module? Or how are the TiCDC requests written? I want to understand the meaning of each request and whether there is room for adjustment.

Take a look at the official manual, it’s more comprehensive.
