I'm not entirely familiar with how the daemon stores these values for the
entire database, but I'm guessing it's done in memory.  Is it not possible
to allocate storage for these values in memory for each table that has been
opened?(they'd be removed once the table is destroyed, and not stored at all
for temporary tables I guess). Another possibility might be to store the
values in memory until the table is no longer in an "open" state (I'm
assuming you don't flush and close the tables on every operation) and flush
them to disk in the table closing code (hopefully reducing the latency of
updating each time they change).

I like the idea of having it saved on disk as it would allow for persistent
values during outages, so long as the system as a whole doesn't take too
much of a performance hit.

What exactly is feature sponsoring?

Hi!

It could be possible to implement it, but it would be more costly, as
data would have to be saved on disk. 

Would you be willing to sponsor this feature ??
