We plan to start working on this problem in a few weeks. Our current
idea is to create a journal format to make a periodic sort of copy of
meta.db as a snapshot.

That copy of meta.db would then be used as a starting point for the
normal journal to be appended to when replaying.

Then periodically, or at a certain journal size, would this snapshot be
made and would the normal journal be truncated (restarted).

Deleted content isn't in meta.db, so not copied to the snapshot. In the
normal journal - part deleted content would still be there, but that
will be periodically truncated.

Anyway, these are just ideas at the moment. But we're planning to work
on a solution soon.

Cheers,

Philip
