By analyzing the source code of Hypertable, the Cellstore’s storage structures have been described. The procedures of reading and writing operations have been introduced. The disadvantages of aforementioned structure have been identified; and the development procedures have been recommended. The development procedures include: combining phase information; building up a phase information table, in order to store high-frequency data. The result shows that the optimal structure can reduce overloaded data in order to improve the efficiency and performance of data reading and writing operations.
