The state and account MPT:s currenty share key space in the database based on that vertex id:s are assigned essentially randomly, which means that when two adjacent slot values from the same contract are accessed, they might reside at large distance from each other. Here, we prefix each vertex id by its root causing them to be sorted together thus bringing all data belonging to a particular contract closer together - the same effect also happens for the main state MPT whose nodes now end up clustered together more tightly. In the future, the prefix given to the storage keys can also be used to perform range operations such as reading all the storage at once and/or deleting an account with a batch operation. Notably, parts of the API already supported this rooting concept while parts didn't - this PR makes the API consistent by always working with a root+vid. |
