Hi again, Naresh! 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.
