Abstract: Storage System for Released Judicial Data (RJDSS) plays an important role in Judicial Publicity Visualisation Analysis System, which can provide convenience for the government and the general public. Released Judicial Data presents a number of challenges to the underlying storage system due to the characteristics of huge amount, wide variety and rapid growth. In order to improve the performance of the upper visualisation system, RJDSS is designed and implemented based on the access features of the released judicial data. Furthermore, it is optimised in system expansion, storage density and read/write performance through such key technologies as scalable distributed storage organisation strategy, highly reliable data dynamic layout mechanism and exponential-decay-based cache algorithm. The experimental results of effectiveness analysis, data import and video playback show that the RJDSS system achieves performance improvement by 3.5x, compared with the existing judicial data storage system.

Keywords: released judicial data; storage system; scalability; I/O performance.
