GBase 8a MPP Cluster offers three primary data distribution strategies: Hash distribution , random distribution , and replicated tables . Each determines how data is physically placed across nodes, directly impacting join and aggregation performance in a gbase database . Strategy Overview Strategy Syntax Distribution Method Key Feature Hash DISTRIBUTED BY (column) Rows with the same column value are mapped to the same node via hash. Data locality — related rows are physically together, ideal for joins and grouping. Random Default (no keyword) or DISTRIBUTED RANDOMLY Data is scattered evenly across all data nodes. Perfect load balancing — equal data volume and compute pressure on every node. Replicated REPLICATED A full copy of the table exists on every data node. Global redundancy — no network transfer needed for joins. When to Use Each Strategy 1.…
