Please elaborate on why it is necessary to create temporary BLOB storage outside of the database.

Commented by: @asfernandes

To have temporary blobs (created by the engine) working in a readonly database, for example.

I think Vlad already implemented temporary space for blobs, but they aren't really used in the engine (except for temporary tables).

But they're available for the user in the API.

This mode will be useful not only for readonly database, but also at selecting of the big number blobs with processing by UDF when occurrence of the big number temporary blobs strongly increases the size of database.
