Seems like splitstore really never got out of testing. It would be nice to get this done, but not only stop by having hot/cold storage, but more important having a feature that automatically prunes the cold store.
Have a variable that controls how many recent-stateroots is held in hot and cold
- Hot behavior: All stateroots > thresshold is moved to cold storage
- Cold behavior: All stateroots > thresshold is deleted/pruned
Outcome: Ongoing static usage of disk space on daemon device
