Which connector allows for internal scheduling based on table rows?

The Database Connector is the correct choice because it provides the capability to perform internal scheduling based on table rows within a database. This allows developers to build applications that can query a database table at scheduled intervals, processing data as it becomes available or responding to changes.

Using the Database Connector, you can set specific timings to execute operations like retrieving rows that meet certain criteria (for example, new rows or rows with a specific status), enabling effective data processing and automation workflows.

In contrast, the other connectors serve different purposes. The HTTP Connector is primarily used for making HTTP requests to web services, the File Connector is designed for operations involving files on a file system, and the FTP Connector facilitates file transfers over the FTP protocol. None of these options provide the specific functionality that the Database Connector does regarding internal scheduling based on table rows.
