Implement Virtual Tree construction VirtualTree (vt) computes a tree without computing any hash. With the idea of once all the leafs are placed in their positions, the hashes can be computed, avoiding computing a node hash more than one time.

Add CPU parallelization to AddBatch CaseD AddBatch in CaseD, is parallelized (for each CPU) until almost the top level, almost dividing the needed time by the number of CPUs.

Add AddBatch CaseD CASE D: Already populated Tree ============================== - Use A, B, C, D as subtree - Sort the Keys in Buckets that share the initial part of the path - For each subtree add there the new leafs R / \ / \ / \ * * / | / \ / | / \ / | / \ L: A B C D /\ /\ / \ / \ ... ... ... ... ... ...

Add CPU parallelization to buildTreBottomUp buildTreeBottomUp splits the key-values into n Buckets (where n is the number of CPUs), in parallel builds a subtree for each bucket, once all the subtrees are built, uses the subtrees roots as keys for a new tree, which as result will have the complete Tree build from bottom to up, where until the log2(nCPU) level it has been computed in parallel. As result of this, the tree construction can be parallelized until almost the top level, almost dividing the time by the number of CPUs.

Add AddBatch CaseC CASE C: ALMOST CASE B --> if Tree has few Leafs (but numLeafs>=minLeafsThreshold) ============================================================================== - Use A, B, G, F as Roots of subtrees - Do CASE B for each subtree - Then go from L to the Root R / \ / \ / \ * * / | / \ / | / \ / | / \ L: A B G D / \ / \ / \ C * / \ / \ / \ ... ... (nLeafs >= minLeafsThreshold)

Add AddBatch CaseB CASE B: ALMOST CASE A, Almost empty Tree --> if Tree has numLeafs < minLeafsThreshold ============================================================================== - Get the Leafs (key & value) (iterate the tree from the current root getting the leafs) - Create a new empty Tree - Do CASE A for the new Tree, giving the already existing key&values (leafs) from the original Tree + the new key&values to be added from the AddBatch call R R / \ / \ A * / \ / \ / \ B C * * / | / \ / | / \ / | / \ L: A B G D / \ / \ / \ C * / \ / \ / \ ... ... (nLeafs < minLeafsThreshold)
