Distributed query optimization in contemporary distributed database system increasingly important role, excellent query optimizer algorithm can effectively improve the query performance of the system. This article will be distributed query optimization hybrid algorithm is applied to improve the performance of distributed query optimization algorithms. Through simulation experiments and comparing two improved algorithms and the merits of the original algorithm, results were analyzed and show that the improved algorithm is better than the original algorithm has been improved to some extent in achieving cost efficiency and other aspects.
