LB-Louvain: Balancing Transaction Locality and Shard Load in Account-Based State Sharding
LB-Louvain is presented, a coarse-to-fine account-partitioning heuristic in which standard Louvain first extracts logical communities, followed by load-aware community-to-shard assignment and restricted boundary-account refinement, and component-wise ablation confirms complementary roles for load-aware assignment and b...
