I would like to associate Files with Big Object records.
Documentation inference implies this is not technically possible... if a Big Object could be a "LinkedEntityId" I imagine it would have been spelled out.
And finally, my attempts to directly associate a ContentDocumentLink with a Big Object record via LinkedEntityId failed. The platform won't allow a save on the ContentDocumentLink.
In light of this... what would be the best-practice way(s) to associate Files with a Big Object records?
