Why I can't View Cursor Field in Replication Tab

It would be good to see the cursor field which Airbyte selects for a connection.

I created the issue in Github to implement this feature https://github.com/airbytehq/airbyte/issues/15448

The reason that no cursor field is shown for streams on a CDC source is because CDC sources use a source-defined cursor, as CDC sources internally keep track of the current position in the replication log (see docs about that https://docs.airbyte.com/understanding-airbyte/cdc). Since they don’t use an actual column of the stream to do this, there is no “cursor field” set for those streams.

Also, a fix was merged in Show "source defined" as cursor for CDC streams, move strings to i18n by edmundito · Pull Request #16999 · airbytehq/airbyte · GitHub which is going to show as source-defined cursor to be more clear when you’re dealing with this situation.
