dev.database-sharding Calculator
Calculates database sharding factor, hotspot risk, and cross-shard query overhead from data volume and access patterns. Sharding by user_id distributes load but makes cross-user queries require scatter-gather across all shards — choose the shard key to match the dominant query pattern.
