In-Memory Worldstate / FlatDB

non-fungible-nelson commented 8 months ago

Description

As a node operator, I may want a way to keep the worldstate in memory for my node. If I have a surplus of RAM, I can keep my worldstate in memory to make calls to this information less IO intensive and quicker.

Need to determine what to do upon shutdown.

How will a node load the world-state in memory?
Should we keep a copy of worldstate on disk as well?
- How often do we flush updates to disk? On shutdown?
How does the node "catch up to head" after a shutdown if the worldstate may be on disk?

Acceptance Criteria

Feature toggle for keeping the flat-DB in memory
Flat DB is not kept on disk but in RAM
SYNC/DISK STRATEGY TBD
