Popis: In parallel database systems, data is partitioned and replicated across multiple independent nodes to improve system performance and increase robustness. In current practice of database partitioning design, all replicas are uniformly partitioned, however, different statements may prefer contradictory partitioning plans, so a single plan cannot achieve the overall optimal performance for the workload.
