Hello Vincent Hou,

We, Manila folks, are about to merge one of new features - "private driver
storage" [1]. That is going to serve for not-user facing data storage
related to any resource that can be reached by both - API and share driver.

And in case of share migration, it will be possible to avoid creation of
"temporary share" DB record and use this data storage for storing all
required data per each share.

Please, look at it, and provide feedback, whether such approach can be used
in your case or not and why.

Kind regards,

Valeriy Ponomaryov
