Re: Datastore warning

[Christian Grothoff]

There are different datastore plugins (sqlite, postgres, mysql). Alas,
that will likely only help a bit.  Ultimately, I think we need to
completely rework the FS subsystem to not store so many small blocks and
instead keep files whole. But that is a very big task nobody is yet
working on. -Christian
