    摘要: Embodiments of the invention enable data to be moved from one or more external sources into a database system. A plurality of processes are executed concurrently. Each of the processes are executable to move data from at least a portion of the one or more external sources into the database system, so that executing the plurality of processes concurrently moves data from different portions of the one or more external sources into the database system in parallel. Execution of the plurality of processes are coordinated from the database system.

    摘要: Methods of inserting data in parallel into a partitioned data storage object are disclosed. Multiple processes are used to insert the data, and multiple processes may insert data into the same partition at the same time. Write conflicts are avoided through use of buffers and a brokering scheme to manage the data flows into the partitioned data storage object. Also disclosed are methods to optimize the size of the buffers to minimize bottlenecks.
