This method is used to build a StageAttachment object which represents a stage in Databend. A stage in Databend is a temporary storage area where data files are stored before being loaded into the Databend database.

Parameters:

connection - The DatabendConnection object which contains the connection details to the Databend database.

stagePath - The path of the stage in the Databend database.

Returns:

A StageAttachment object which contains the details of the stage.
