Ordering, Distinctness, Aggregation, Partitioning and DQP Optimization in Sybase ASE 15
Summary: Semantic partitions and a rewritten QP enable parallelism on partitioned ASE tables. Plan-fragment framework unifies ordering, distinctness, aggregation, partitioning, and DQP; Abstract Plan enables user-forced, valid plans with modest optimizer growth.
