if we keep all the pivot blocks used during snapsync you can completely skip the fladb healing if all the pivot blocks used are canonical and only trigger the heal if one of the block is not canonical

Not necessarily all pivots, as we already discussed. It's a valid point but hopefully you don't want to address it in this PR :)

in another PR I think it will be better to download the BAL before in the pipeline where we are downloading header, body

Pass the first pivot, stored in
ChainSyncStateand persisted inChainSyncStateStorage, throughSnapSyncProcessStatetoSnapWorldDownloadState(+ make sure to preserve it when recreatingSnapSyncProcessStateinSnapSyncDownloader#storeState) where it is used incheckCompletionto decide whether BAL requests should be enqueued. Due to dependencies between request queues, enqueueing BAL requests blocks flat db requests. This means that BALs are applied (when necessary) strictly after trie healing and before flat db healing phase. Moreover, BAL request enqueuing is gated behindAtomicBoolean(+checkCompletionis synchronized) to happen only once.Batched BAL responses are then passed through
PersistDataStep#persisttoBlockAccessListDataRequest#doPersistwhere they are applied to the providedBonsaiWorldStateKeyValueStorage.Updaterand later committed to storage. We make sure to recompute the storage root if any slots were modified.Some functionality shared with
BalStateRootCalculator(where BALs are applied to world state in a similar way) was extracted toBlockAccessListChanges. This results in extra copy - not sure about performance impact.Follow up PR will introduce a functionality to the
Pipelinewhich will allow to aggregate batches of items into a single batch, so that all changes from BALs are applied to the same updater and committed in one atomic operation.
