I'm a .net developer new to working with the centera sdk. Basically what I am trying to do is loop through blobs of data stored in a database and send them off to a centera device. I was able to get this working but only by opening and closing the connection for each blob. With millions of files to loop through this in not efficient since it takes a few seconds to open the connection and authenticate. Is there any documentation or code examples of how to open the connection once, write all files, then close connection at the end?
