| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, stream data have been increasing by the development of sensing devices such as sensors, GPS and network cameras. One of the requirements of stream data is to provide persistence for analysis. We focused on providing duplicative persistence, and achieved fast persisting process by optimizing the processing tree. But this method ignore rewriting process that rewrite persisted data to data area. We propose a method that makes persisted data to original result. First we discuss a naive method. The method decreases persistent performance because rewriting process includes disk access. Then we propose a method that rewrites the data without harming persisting process. It is possible to rewrite without harming persisting process by control rewriting processing time. And we prove the effectiveness of proposed method through an experiment. Naive method can't persist data at 5 tuples/sec. On the other hand, proposed method can persist data until 15 tuples/sec. | |
