Delete data from blob

[brollb]

It would be nice to be able to delete data from the blob when we know that it will not be used anymore. One such example is values uploaded to the blob for use with a plugin.

Due to the nature of the blob, that is not feasible (data stored by content-based hash meaning the id can point to other artifact that should not be removed).
If this is urgent, I would introduce some alternative storage that is accessible for a plugin (via a router, or using the server's file system directly).

On the other hand, we are working on a temporary blob storage that would be servicable and could be emptied when the server is down...

Didn’t we add a cleanup-script for the file system blob? It looked at all blobhash like properties in the database blobs and made a blacklist.
