I want to use TICDC to capture incremental information of tables in the INFORMATION_SCHEMA database. However, the official documentation says that the default configuration does not support this.

Use SQL to poll and retrieve… ticdc is mainly used to solve the problem of obtaining incremental business data…

Alright… Because polling is too slow, I was thinking if it could be done through TiCDC. Since that’s the case, I’ll use the polling method.

I also checked, it is not supported.
