対訳 パーティション テーブルの並列処理

解説

• The parallel execution strategy for queries that select from partitioned objects. As part of the execution strategy, the query processor determines the table partitions that are required for the query and the proportion of threads to allocate to each partition. In most cases, the query processor allocates an equal or almost equal number of threads to each partition, and then executes the query in parallel across the partitions.
