Hongshun Wang commented on FLINK-37479:
---------------------------------------

[~phamvinh1712] As I discussed in [https://docs.google.com/document/d/10ndYF3aORwRaeEElO1pSE9WRVoxa1vJrnleqi0HHWq8/edit?tab=t.0 |https://docs.google.com/document/d/10ndYF3aORwRaeEElO1pSE9WRVoxa1vJrnleqi0HHWq8/edit?tab=t.0]

It's not easy to support it because cdc's shouldEmit logical.

Currently, using a regular expression for the table name can achieve a similar effect, but it is not as elegant.

> At the moment, Postgresql connector doesn't support discover PARTITIONED TABLE, making the connector not possible to take snapshot on partitioned table.
