• Some comletions might be needed for the aristo_part module which is a re-implementation of the module supporting proof-mode/partial trees.

  • Complete partMergeStorageData(). This function might not be needed at all unless snap-sync is really revived.
  • For snap-sync, write a proof function verifying whether the partial tree is correct relative to the PartStateRef descriptor.
  • One might need to re-visit the removeCompletedNodes() module when using snap-sync proof features. The algorithm used here assumes that the list of proof nodes is rather small. Also, a right boundary leaf node is typically cleared. This needs to be re-checked when writing the proof function mentioned above.

• aristo_nearby also qualifies for a re-write, now

• Revisit tree deletion. The idea is to finally use ranges of nodes by exploiting the root ID prefix of a RootedVertexID. The RocksDb backend seems to support this kind of operation, see https://rocksdb.org/blog/2018/11/21/delete-range.html. For the application part there are some great ideas floating which need to be followed up some time.
