const HashScheme = "hashScheme"

HashScheme is the legacy hash-based state scheme with which trie nodes are stored in the disk with node hash as the database key. The advantage of this scheme is that different versions of trie nodes can be stored in disk, which is very beneficial for constructing archive nodes. The drawback is it will store different trie nodes on the same path to different locations on the disk with no data locality, and it's unfriendly for designing state pruning.

Now this scheme is still kept for backward compatibility, and it will be used for archive node and some other tries(e.g. light trie).

View Source 
const PathScheme = "pathScheme"

PathScheme is the new path-based state scheme with which trie nodes are stored in the disk with node path as the database key. This scheme will only store one version of state data in the disk, which means that the state pruning operation is native. At the same time, this scheme will put adjacent trie nodes in the same area of the disk with good data locality property. But this scheme needs to rely on extra state diffs to survive deep reorg.
