000000490 520__ $$aAt the begging of the Belle experiment, every extracted subset data from full-set data has been stored in “mini-data-structure-table” (mdst) format. However, these files have occupied so much disk space, which causes suffer from the lack of disk space. To solve the problem, Belle  experiment composed the extraction of full-set data  based  on database which is postgreSQL, At the Belle II    experiment, we will have 50~60 times more data (~120 PB) than  that of the  Belle experiment. Therefore, the Belle II  experiment will  have experienced a   few problems for the lack of disk space and the limitation of database in gridsystem. Therefore, we propose applying the data cache system based on compressed text.
