摘要
A system and method of responding to a database query. A query is received for MPP database data stored on a plurality of processing systems. A total splits number of the database data, each split containing at least a portion of the database, is determined. If the total splits number splits is greater than a splits threshold number, partial task maps are created and streamed to the processing systems after compiling the query. If the total splits number is less than the splits threshold number, a complete task map for all splits is created and output to the plurality of processing systems.
