## Issue Addressed Successor to #2431 ## Proposed Changes * Add a `BlockReplayer` struct to abstract over the intricacies of calling `per_slot_processing` and `per_block_processing` while avoiding unnecessary tree hashing. * Add a variant of the forwards state root iterator that does not require an `end_state`. * Use the `BlockReplayer` when reconstructing states in the database. Use the efficient forwards iterator for frozen states. * Refactor the iterators to remove `Arc<HotColdDB>` (this seems to be neater than making _everything_ an `Arc<HotColdDB>` as I did in #2431). Supplying the state roots allow us to avoid building a tree hash cache at all when reconstructing historic states, which saves around 1 second flat (regardless of `slots-per-restore-point`). This is a small percentage of worst-case state load times with 200K validators and SPRP=2048 (~15s vs ~16s) but a significant speed-up for more frequent restore points: state loads with SPRP=32 should be now consistently <500ms instead of 1.5s (a ~3x speedup). ## Additional Info Required by https://github.com/sigp/lighthouse/pull/2628 |
