/**
* A class to manage metadata for upload or download files. It is introduced for distributed data
* processing. The typical use case is: 1. The cluster master has JDBC connection to the Snowflake
* and it can generate this object for the file transfer. 2. The cluster master node can transfer
* the object to cluster worker. 3. The cluster worker can upload or download data with the object
* without JDBC Connection.
*
* NOTE: When this class is created, it only supports UPLOAD for GCS. It is created for Snowflake
* Spark Connector.
