does sftp bulk connector support set first row as header?

Hmm, I don't know enough to give you a confident answer yet. The provided knowledge sources do not explicitly mention whether the SFTP Bulk connector supports setting the first row as a header. For more detailed information, you can refer to the [SFTP Bulk connector documentation](https://docs.airbyte.com/integrations/sources/sftp-bulk) or check the [Airbyte GitHub repository](https://github.com/airbytehq/airbyte) for any related issues or discussions.
