能劣化的问题。 网络带宽资源 为了实现查询并行执行，会新增并行线程间的数据交换算子。对于Local类Stream算子，所需要进行数据交换的线程在同一个DN内，通过内存交换，不会增加网络负担。而非Local类算子，需要通过网络进行数据交换，因此会加重网络负担。当网络资源成为瓶颈的情况下，并行可能会导致一定程度的劣化。
入到GaussDB(DWS)中，如图1所示。各导入方式具有不同的特点，如表1所示，用户可以根据其特点自行选择。建议用户配合云数据迁移（Cloud Data Migration，简称CDM）和数据治理中心（DataArts Studio）一起使用，CDM用于批量数据迁移，DataArts
